Add the first typical (non-sanitization) consumer of the new background
command infrastructure, firmware update. Given both firmware-update and
sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.

Pick up the sanitization work and the infrastructure for other
background commands for 6.5. Sanitization has a different completion
path than typical background commands so it was important to have both
thought out and implemented before either went upstream.

Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW'
CXL mailbox commands to the cxl_test emulated memdevs to enable
end-to-end unit testing of a firmware update flow. For now, only
advertise an 'offline activation' capability as that is all the CXL
memdev driver currently implements.

Add some canned values for the serial number fields, and create a
platform device sysfs knob to calculate the sha256sum of the firmware
image that was received, so a unit test can compare it with the original
file that was uploaded.

The sysfs based firmware loader mechanism was created to easily allow
userspace to upload firmware images to FPGA cards. This also happens to
be pretty suitable to create a user-initiated but kernel-controlled
firmware update mechanism for CXL devices, using the CXL specified
mailbox commands.

Since firmware update commands can be long-running, and can be processed
in the background by the endpoint device, it is desirable to have the
ability to chunk the firmware transfer down to smaller pieces, so that
one operation does not monopolize the mailbox, locking out any other
long running background commands entirely - e.g. security commands like
'sanitize' or poison scanning operations.

The firmware loader mechanism allows a natural way to perform this
chunking, as after each mailbox command, that is restricted to the
maximum mailbox payload size, the cxl memdev driver relinquishes control
back to the fw_loader system and awaits the next chunk of data to
transfer. This opens opportunities for other background commands to
access the mailbox and send their own slices of background commands.

Add the necessary helpers and state tracking to be able to perform the
'Get FW Info', 'Transfer FW', and 'Activate FW' mailbox commands as
described in the CXL spec. Wire these up to the firmware loader
callbacks, and register with that system to create the memX/firmware/
sysfs ABI.

Implement support for the non-pmem exclusive secure erase, per
CXL specs. Create a write-only 'security/erase' sysfs file to
perform the requested operation.

As with the sanitation this requires the device being offline
and thus no active HPA-DPA decoding.

The expectation is that userspace can use it such as:

Implement support for CXL 3.0 8.2.9.8.5.1 Sanitize. This is done by
adding a security/sanitize' memdev sysfs file to trigger the operation
and extend the status file to make it poll(2)-capable for completion.
Unlike all other background commands, this is the only operation that
is special and monopolizes the device for long periods of time.

In addition to the traditional pmem security requirements, all regions
must also be offline in order to perform the operation. This permits
avoiding explicit global CPU cache management, relying instead on the
implict cache management when a region transitions between
CXL_CONFIG_ACTIVE and CXL_CONFIG_COMMIT.

The expectation is that userspace can use it such as:

    cxl disable-memdev memX
    echo 1 > /sys/bus/cxl/devices/memX/security/sanitize
    cxl wait-sanitize memX
    cxl enable-memdev memX

Sanitization is by definition a device-monopolizing operation, and thus
the timeslicing rules for other background commands do not apply.
As such handle this special case asynchronously and return immediately.
Subsequent changes will allow completion to be pollable from userspace
via a sysfs file interface.

For devices that don't support interrupts for notifying background
command completion, self-poll with the caveat that the poller can
be out of sync with the ready hardware, and therefore care must be
taken to not allow any new commands to go through until the poller
sees the hw completion. The poller takes the mbox_mutex to stabilize
the flagging, minimizing any runtime overhead in the send path to
check for 'sanitize_tmo' for uncommon poll scenarios.

The irq case is much simpler as hardware will serialize/error
appropriately.

Move GMU mutex initialization earlier to make sure that it is always
initialized. a6xx_destroy can be called from ther failure path before
GMU initialization.

This fixes the following backtrace:

The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to
false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller
case. HDP related interrupts can not be enabled until internal_hpd is set
to true. At current implementation dp_display_config_hpd() will initialize
DP host controller first followed by enabling HDP related interrupts if
internal_hpd was true at that time. Enable HDP related interrupts depends on
internal_hpd status may leave system with DP driver host is in running state
but without HDP related interrupts being enabled. This will prevent external
display from being detected. Eliminated this dependency by moving HDP related
interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly
regardless of internal_hpd status.

Changes in V3:
-- dp_catalog_ctrl_hpd_enable() and dp_catalog_ctrl_hpd_disable()
-- rewording ocmmit text

Changes in V4:
-- replace dp_display_config_hpd() with dp_display_host_start()
-- move enable_irq() at dp_display_host_start();

Changes in V5:
-- replace dp_display_host_start() with dp_display_host_init()

Changes in V6:
-- squash remove enable_irq() and disable_irq()
