[Intel-gfx] [PATCH v3 06/11] drm/i915: Move intel_format_info_is_yuv_semiplanar() to intel_fb.c

[Imre Deak <imre.deak@intel.com>]

Move intel_format_info_is_yuv_semiplanar() to intel_fb.c . The number of
planes for YUV semiplanar formats using CCS modifiers will change on
future platforms. We can use the modifier descriptors to simplify
getting the plane numbers for all modifiers, prepare for that here.
