[PATCH v2] drm/fourcc: Fix modifier field mask for AMD modifiers.

[Bas Nieuwenhuizen]

The DCC_MAX_COMPRESSED_BLOCK has to contain one of
AMD_FMT_MOD_DCC_BLOCK_* and with 3 values this doesn't
fit in 1 bit.

Fix this cleanly while it is only in drm-next.

Fixes: 8ba16d599374 ("drm/fourcc: Add AMD DRM modifiers.")
