drm/i915: don't warn about Skylake CPU - KabyPoint PCH combo
Apparently there are machines out there with Skylake CPU and KabyPoint PCH. Judging from our driver code, there doesn't seem to be any code paths that would do anything different between SunrisePoint and KabyPoint PCHs, so it would seem okay to accept the combo without warnings. Fixes: 22dea0be50b2 ("drm/i915: Introduce Kabypoint PCH for Kabylake H/DT.")
