During the testing of Gnome on Qualcomm Robotics platform screen
corruption has been observed. Lowering GPU's highest_bank_bit from 14 to
13 seems to fix the screen corruption.
Note, the MDSS and DPU drivers use HBB=1 (which maps to the
highest_bank_bit = 14). So this change merely works around the UBWC
swizzling issue on this platform until the real cause is found.
