[PATCH RFT 13/14] drm/msm/a6xx: Drop cfg->ubwc_swizzle override

From: Konrad Dybcio <konrad.dybcio at oss.qualcomm.com>

On A663 (SA8775P) the value matches exactly.

On A610, the value matches on SM6115, but is different on SM6125. That
turns out not to be a problem, as the bits that differ aren't even
interpreted.
