Now that we have a helper to gather periodic
endpoints' multiplier bits from wMaxPacketSize and
every driver is using it, we can safely make sure
that usb_endpoint_maxp() returns only bits 10:0 of
wMaxPacketSize which is where the actual packet size
lies.

There might be situations where a Start Transfer

No Response Update Transfer is a special type of
Update Transfer command which can be used whenever
we're not relying on XferNotReady to prepare
transfers. With this, we don't need to wait for
CMDACT to be cleared and issue further commands to
the endpoint straight away.

Let's start using this version to skip the long-ish
wait.

The cmd argument we pass to
dwc3_send_gadget_ep_cmd() could contain extra
arguments embedded. When checking for StartTransfer

bits which contain the actual command and ignore the
rest.

In case of High-Speed, High-Bandwidth endpoints, we
need to tell DWC3 that we have more than one packet
per interval. We do that by setting PCM1 field of
Isochronous-First TRB.

Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

ep->mult is supposed to be set to Isochronous and
Interrupt Endapoint's multiplier value. This value
is computed from different places depending on the
link speed.

If we're dealing with HighSpeed, then it's part of
bits [12:11] of wMaxPacketSize. This case wasn't
taken into consideration before.

While at that, also make sure the ep->mult defaults
to one so drivers can use it unconditionally and
assume they'll never multiply ep->maxpacket to zero.

usb_endpoint_maxp() returns wMaxPacketSize in its
raw form. Without taking into consideration that it
also contains other bits reserved for isochronous
endpoints.

This patch fixes one occasion where this is a
problem by making sure that we initialize
ep->maxpacket only with lower 10 bits of the value
returned by usb_endpoint_maxp(). Note that seperate
patches will be necessary to audit all call sites of
usb_endpoint_maxp() and make sure that
usb_endpoint_maxp() only returns lower 10 bits of
wMaxPacketSize.

According to USB Specification 2.0 table 9-4,
wMaxPacketSize is a bitfield. Endpoint's maxpacket
is laid out in bits 10:0. For high-speed,
high-bandwidth isochronous endpoints, bits 12:11
contain a multiplier to tell us how many
transactions we want to try per uframe.

This means that if we want an isochronous endpoint
to issue 3 transfers of 1024 bytes per uframe,
wMaxPacketSize should contain the value:

	1024 | (2 << 11)

or 5120 (0x1400). In order to make Host and
Peripheral controller drivers' life easier, we're
adding a helper which returns bits 12:11. Note that
no care is made WRT to checking endpoint type and
gadget's speed. That's left for drivers to handle.

Pull x86 bugfix from Thomas Gleixner:
 "A single bugfix for the recent changes related to registering the boot
  cpu when this has not happened before prefill_possible_map().

  The main problem with this change got fixed already, but we missed the
  case where the local APIC is not yet mapped, when prefill_possible_map()
  is invoked, so the registration of the boot cpu which has the APIC bit
  set in CPUID will explode.

  I should have seen that issue earlier, but all I can do now is feeling
  embarassed"
