Add -ENODEV to the list of usb-transfer errors which we ignore to
avoid logging Frame update errors when the device gets unplugged.

I made the condition of the wait_event_timeout call in
gm12u320_fb_update_work a helper which takes a mutex to make sure
that any writes to fb_update.run or fb_update.fb from other CPU cores
are seen before the check is done.
This is not necessary as the wait_event helpers contain the necessary
barriers for this themselves.
More over it is harmfull since by the time the check is done the task
is no longer in the TASK_RUNNING state and calling mutex_lock while not
in task-running is not allowed, leading to this warning when the kernel
is build with some extra locking checks enabled:
[11947.450011] do not call blocking ops when !TASK_RUNNING; state=2 set at
[<00000000e4306de6>] prepare_to_wait_event+0x61/0x190
This commit fixes this by dropping the helper and simply directly
checking the condition (without unnecessary locking) in the
wait_event_timeout call.

Previously the driver was using a mix of DRM_ERROR and dev_err, be
consisent and use DRM_DEV_ERROR everywhere instead.

3 small cleanups:
1) Drop unused DRIVER_PATCHLEVEL
2) We do not set mode_config.preferred_depth, so instead of passing the
unset mode_config.preferred_depth to drm_fbdev_generic_setup
simply pass 0
3) Use __maybe_unused instead of #ifdef CONFIG_PM around the suspend /
resume functions
