Add a way to hint to the fence signaler of an upcoming deadline, such as
vblank, which the fence waiter would prefer not to miss. This is to aid
the fence signaler in making power management decisions, like boosting
frequency as the deadline approaches and awareness of missing

This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.
This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:

Add a build option to disable modesetting support. This is useful in
cases where the guest only needs to use the GPU in a headless mode, or
(such as in the CrOS usage) window surfaces are proxied to a host
compositor.
v2: Use more if (IS_ENABLED(...))
v3: Also permit the host

Add a new flag to let userspace provide a deadline as a hint for syncobj
and timeline waits. This gives a hint to the driver signaling the
backing fences about how soon userspace needs it to compete work, so it
can addjust GPU frequency accordingly. An immediate deadline can
