drm/i915: Introduce IS_GEN9_BC for Skylake and Kabylake.
Along with GLK it was introduced the .is_lp and IS_GEN9_LP.
So, following the same simplification standard we can
put Skylake and Kabylake under the same bucket for most
of the things.
So let's add the IS_GEN9_BC for "Big Core" (non Atom based
platforms).
The i915_drv.c was let out of this patch on purpose
because that is really a decision per platform, just like
other cases where IS_KABYLAKE is different from IS_SKYLAKE.
v2: fix conflict with IS_LP and 3 new cases for this
big core bucket:
- intel_ddi.c: intel_ddi_get_link_dpll
- intel_fbc.c: find_compression_threshold
- i915_gem_gtt.c: gtt_write_workarounds
