drm/i915: move power domain init earlier during system resume

drm/i915: move power domain init earlier during system resume

During resume the intel hda audio driver depends on the i915 driver
reinitializing the audio power domain. Since the order of calling the
i915 resume handler wrt. that of the audio driver is not guaranteed,
move the power domain reinitialization step to the resume_early
handler. This is guaranteed to run before the resume handler of any
other driver.

The power domain initialization in turn requires us to enable the i915
pci device first, so move that part earlier too.

Accordingly disabling of the i915 pci device should happen after the
audio suspend handler ran. So move the disabling later from the i915
resume handler to the resume_late handler.

v2:
- move intel_uncore_sanitize/early_sanitize earlier too, so they don't
  get reordered wrt. intel_power_domains_init_hw()
