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%[email protected] for the gory
details as to why it triggers with older gccs only.
