drm/i915/display: move HSW and BDW clock gating init to display

Move the HSW and BDW display clock gating programming into the display
code. In this case we need two different helpers, because the common
code between these two is split in the middle.

drm/i915/display: move GLK clock gating init to display

Move the GLK-specific display clock gating programming into display
intel_display_clock_gating.c, to remove more dependencies from i915 to
display registers.

Now that all remaining Gen9-family callers moved into display, we can
move the shared Gen9 display clock gating helper into display and
remove the old local helper from intel_clock_gating.c.

Additionally, the SKL_DE_COMPRESSED_HASH_MODE programming was
protected by HAS_LLC(), but that's incidental, because in Gen9
platforms, only SKL and KBL, for which this workaround applies, have
LLC(). In order not to use HAS_LLC() in display code, we can simply
remove this check from the generic Gen9 function and move the
SKL_DE_COMPRESSED_HASH_MODE programming to the KBL and SKL specific
functions. And, intentionally or not, CFL and CML were also using
this workaround, because they also have LLC, even though the comments
were only mentioning SKL and KBL. In order not to change anything
functionally with this patch, the workaround was also added to
intel_display_cfl_init_clock_gating().
