drm/i915: add opregion function to notify bios of encoder enable/disable
The bios interface seems messy, and it's hard to tell what the bios
really wants. At first, only add support for DDI based machines (hsw+),
and see how it turns out.
The spec says to notify prior to power down and after power up. It is
unclear whether it makes a difference.
v2:
- squash notification function and callers patches together (Daniel)
- move callers to haswell_crtc_{enable,disable} (Daniel)
- rename notification function (Chris)
v3:
- separate notification function and callers again, as it's not clear
whether the display power state notification is the right thing to do
after all
v4: per Paulo's review:
- drop LVDS
- WARN on unsupported encoder types
