I suggest we have both drivers just available first and then attempt
to deal with the removal of most of omap-serial later on.

If both drivers are present, we should try to ensure 8250 gets probed
first which I believe it already does based on the Makefile order.

Once the 8250 based driver is known to work, it might make sense to
remove most of the functions in omap-serial and have it use the 8250
functions too to remove duplicate code.

That might be already enough and no proxying is needed and we get
rid of the duplicate code :)

Regards,

Tony
