drm/msm/dpu: Disable broken YUV on QSEED2 hardware

Browse Source 
YUV formats on this hardware needs scaling for chroma planes. However it
is not implemented for QSEED2 which breaks display pipeline if YUV format
is used (causing partial and corrupted output with PPDONE timeouts).
This patch temporarily disables YUV by switching affected sub-block to
RGB only format list.
