hid-alps driver cleanups wrt. t4_read_write_register() handling
from Christophe Jaillet

When we receive a RMI4 report, we should not unconditionally send an
input_sync event. Instead, we should let the rmi4 transport layer do it
for us.

This fixes a situation where we might receive X in a report and the rest
in a subsequent one. And this messes up user space.

According to [1] and also seemingly agreed by [2], the Scan Time usage
(0x0D 0x56) is a report level usage, not a contact level usage.

However, the hid-multitouch driver currently includes HID_DG_SCANTIME
when calculating `td->last_slot_field', which may lead to
mt_complete_slot() being prematurely called in certain cases (e.g. when
each touch input report includes more than one contact and the Scan Time
usage appears before any contact logical collection).

This patch fixes the issue by skipping mt_store_field() on
HID_DG_SCANTIME, similar to how HID_DG_CONTACTCOUNT and
HID_DG_CONTACTMAX are handled.

The wireless Steam Controller is battery operated, so add the battery
device and power information.
Signed-off-by: Jiri Kosina <jkosina@suse.cz>

There are two ways to connect the Steam Controller: directly to the USB
or with the USB wireless adapter.  Both methods are similar, but the
wireless adapter can connect up to 4 devices at the same time.

The wired device will appear as 3 interfaces: a virtual mouse, a virtual
keyboard and a custom HID device.

The wireless device will appear as 5 interfaces: a virtual keyboard and
4 custom HID devices, that will remain silent until a device is actually
connected.

The custom HID device has a report descriptor with all vendor specific
usages, so the hid-generic is not very useful. In a PC/SteamBox Valve
Steam Client provices a software translation by using hidraw and a
creates a uinput virtual gamepad and XTest keyboard/mouse.

This driver intercepts the hidraw usage, so it can get out of the way
when the Steam Client is in use.

The root cause of the problem is starting hrtimer with an expiry time
already in the past can take more than 20 milliseconds to trigger the
timer function.  It can be solved by forward such past timers
immediately, rather than submitting them to hrtimer_start().
In case the timer is periodic, update the target expiration and call
hrtimer_start with it.

v2: Check if the tsc deadline is already expired. Thank you Mika.
v3: Execute the past timers immediately rather than submitting them to
hrtimer_start().
v4: Rearm the periodic timer with advance_periodic_target_expiration() a
simpler version of set_target_expiration(). Thank you Paolo.
