i915 / PM: Fix hibernate regression caused by suspend/resume splitting
Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash
while aborting hibernation) attempted to fix a regression introduced
by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915:
implement new pm ops for i915), but it went too far trying to split
the freeze/suspend and resume/thaw parts of the code. As a result,
it introduced another regression, which only is visible on some systems.
Fix the problem by merging i915_drm_suspend() with
i915_drm_freeze() and moving some code from i915_resume()
into i915_drm_thaw(), so that intel_opregion_free() and
intel_opregion_init() are also executed in the freeze and thaw code
paths, respectively.
