kms/impl-device: Inhibit deadline timer on vc4 (Raspberry Pi)
vc4's implementation of drmModeAtomicCommit
seems to require a few
milliseconds advanced notice or else it will miss the frame deadline.
That's too high for our deadline evasion threshold which is measured
in microseconds. Let's stop trying to use deadline timers on vc4 to
avoid this conflict without having to disable atomic KMS.
