The UAPI change needs to be separately contributed to Linux directly, not this fork.

For experimenting we should move this into the driver with
#ifndef DRM_FORMAT_MOD_APPLE_INTERCHANGE_COMPRESSED
#define DRM_FORMAT_MOD_APPLE_INTERCHANGE_COMPRESSED fourcc_mod_code(APPLE, 3)
#endif
I'm not sure if we want one or more APPLE_INTERCHANGE_COMPRESSED modifiers to handle YCbCr formats which use 32x32 tiles for Y
