drm/i915/display: move clock-gating init for IBX to display

Browse source

Add a new function in the display code to help initialize clock-gating
without reading display PCH registers directly from non-display code.

This adds a mini-framework to deal with display-specific PCH registers
and uses it for IBX as a start.
