[PATCH v3 0/8] drm/i915: move more display dependencies from i915

This series continues my work of refactoring the clock gating
initialization, so that i915 doesn't do display-specific stuff.

With this, all register dependencies should be gone.

Changes in v3, mostly addressing Jani's comments:

* Changed the shared Gen9 display clock gating helper not to
include i915_drv.h, to_i915() and HAS_LLC();
* Kept SKL_DE_COMPRESSED_HASH_MODE out of the shared Gen9
helper and programmed it only from the SKL/KBL wrappers;
* Moved the remaining ILK display register definitions from
i915_reg.h to intel_display_regs.h;
* Removed i915_reg.h from intel_display_clock_gating.c;
* Replaced i915-only platform checks in display code with
display->platform.* checks;

Please review.

Cheers,
Luca.
