anv: Disable CCS_E for ISL_FORMAT_YCRCB_*

We're about to start using YCRCB_NORMAL and YCRCB_SWAPUV for 8-bit
interleaved YCbCr and, while ISL claims CCS_E support, it's not well
tested and we don't think it's working yet for all of ANV's use-cases.
Disable it for now in ANV and only for YUV formats.
