In order to support the "enable GPIO" available in many panel devices,
this commit adds a proper devicetree binding.
By providing an enable GPIO in the devicetree, the driver can now turn
off and on the panel device, and/or the backlight device. Both the

The problem with the current implementation is that adding a timer improperly
checked which process would time up first by not taking into account how much
time elapsed since their timer got scheduled. Rework the re-scheduling
decision t fix this.
The catch with this fix is that we are limited to scheduling timers of up to
2^31 ticks to avoid any potential overflow. Since we are unlikely to need to
wait for more than a second, this won't be a problem :)
Another possible fix would be to decrement the timeouts of all processes but
it would duplicate a lot of code and dealing with edge cases wasn't pretty
last time I checked.

drm: Drop modeset locking from crtc init function
At driver init no one can access modeset objects and we're
single-threaded. So locking is just cargo-culting here. Worse, with
the new ww mutexes and ww mutex slowpath debugging the mutex_lock
might actually fail, and we don't have the full-blown ww recovery
dance.
Which then leads to fireworks when we try to unlock the not-locked
crtc lock.
An audit of all the functions called from here shows that none of them
contain locking checks, so there's also no reason to keep the locking
around just for consistency of caller contexts. Besides that I have
the rule (at least in i915) that such places where we take locks just
to simplify locking checks and not for correctness always require a
comment.
