drm/i915: Drop 64bpp YUV formats from ICL+ SDR planes
I'm seeing underruns with these 64bpp YUV formats on TGL.
The weird details:
- only happens on pipe B/C/D SDR planes, pipe A SDR planes
seem fine, as do all HDR planes
- somehow CDCLK related, higher CDCLK allows for bigger plane
with these formats without underruns. With 300MHz CDCLK I
can only go up to 1200 pixels wide or so, with 650MHz even
a 3840 pixel wide plane was OK
- ICL and ADL so far appear unaffected
So not really sure what's the deal with this, but bspec does
state "64-bit formats supported only on the HDR planes" so
let's just drop these formats from the SDR planes. We already
disallow 64bpp RGB formats.
