drm/i915/dmc_wl: Use non-sleeping variant of MMIO wait
Some display MMIO transactions for offsets in the range that requires
the DMC wakelock happen in atomic context (this has been confirmed
during tests on PTL). That means that we need to use a non-sleeping
variant of MMIO waiting function.
Implement __intel_de_wait_for_register_atomic_nowl() and use it when
waiting for acknowledgment of acquire/release.
v2:
- No __intel_de_wait_for_register_atomic_nowl() wrapper to convert
i915 to display. (Jani)
- Add a quick explanation why DMC_WAKELOCK_CTL_TIMEOUT_US is defined
in microseconds. (Luca)
