drm/r128: Fix undefined behavior due to shift overflowing the constant
Fix:
drivers/gpu/drm/r128/r128_cce.c: In function ‘r128_do_init_cce’:
drivers/gpu/drm/r128/r128_cce.c:417:2: error: case label does not reduce to an integer constant
case R128_PM4_64BM_64VCBM_64INDBM:
^~~~
drivers/gpu/drm/r128/r128_cce.c:418:2: error: case label does not reduce to an integer constant
case R128_PM4_64PIO_64VCPIO_64INDPIO:
^~~~
See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
