drm/i915/opregion: use generic poll_timeout_us() instead of wait_for()
Prefer generic poll helpers over i915 custom helpers.
The functional change is losing the exponentially growing sleep of
wait_for(), which used to be 10, 20, 40, ..., 640, and 1280 us.
Use an arbitrary constant 1 ms sleep instead. The timeout remains, being
opregion defined, 50 ms by default, and 1500 ms at most.
