[PATCH] drm/r128: fix compilation errors caused by `-fsanitize=shift`

[GONG, Ruiqi]

Fix the following compilation errors that are produced by building
recent mainline code on arm64 with `allmodconfig`:

  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:
    ^~~~

These errors are induced by `-fsanitize=shift`.
