Funny, is_imx6q_uart() was introduced in
a496e6284c482555db8078190bb689594d129fa9 and never used. Since that
commit is_imx21_uart() also unused. And the imx53 variant was also never
used.
Looking at that a bit more, the following cleanup is also possible (only
compile tested):

If you feel like squashing that into your commit or put it into a
separate commit with a nice commit log (after convincing yourself that
the change is fine), feel free to do so.
If you don't:
