[0/6] drm/i915/opregion: better abstractions

Message

Here's some opregion refactoring and abstraction inspired by
Radhakrishna's series [1]. This is basically what I want to see done
first.

The next step would be to move VBT firmware loading from
intel_opregion_setup() to intel_bios_setup(). This probably involves
keeping a copy of the VBT around in i915->display.vbt, maybe add vbt and
vbt_size members there. This can be used to fix the i915_vbt debugfs
file to actually reflect the VBT wherever it came from.


BR,
Jani.
