[PATCH 7/7] drm/{i915, xe}: Move power_domains suspend/resume to display_power

[Rodrigo Vivi]

Move intel_power_domains_{suspend,resume} to inside
intel_display_power_{suspend_late, resume_early}.

With this also change the VLV suspend failure to call
the intel_display_power_resume_early. In the end, the only
function executed there for VLV is the intel_power_domains_resume.
Besides make the code more consistency give the call that was
immediately before: intel_display_power_suspend_late.
