This has been an established practice at least in the media tree. The
MAINTAINERS change is small, and bindings come before the driver. And the
MAINTAINERS change needs to come no later than files are being added, or a
checkpatch.pl warning follows --- which is entirely reasonable. You could
put the MAINTAINERS change to a separate patch, yes, but I personally think
it fits fine with the DT binding patch.
