serial: omap: Only allow if 8250_omap is not selected
For years we've been carrying legacy omap-serial in addition to
8250_omap driver and 8250_omap should be used instead.
Let's finally start planning on removing omap-serial by first not
building it if 8250_omap is selected to save some memory.
The defconfigs have switched over to using 8250_omap, and we have
a fixup in place for the the serial console since commit 00648d0282
("tty: serial: 8250: omap: add ttySx console if the user didn't").
So people updating their systems without omap-serial will see
boot time warnings on what is going on.
