[PATCH RFT v4 11/14] soc: qcom: ubwc: Fix SM6125's ubwc_swizzle value

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

The value of 7 (a.k.a. GENMASK(2, 0), a.k.a. disabling levels 1-3 of
swizzling) is what we want on this platform (and others with a UBWC
1.0 encoder).

Fix it to make mesa happy (the hardware doesn't care about the 2 higher
bits, as they weren't consumed on this platform).
