Implement register polling directly in the display code
In an effort to decouple the display code from i915/xe.

This is just the first step in a larger display mmio rework.
My final aim is to move the entire mmio stuff into the display
code. That will give us:
- better control over how things are done
- decouple display register locking from forcewake/etc
- less overhead. We access a lot of registers, and
  during vblank evasion critical section performance is
  especially important.
- unified RMbus unclaimed error checking for both i915 and xe
