sh: More flexible + SH7780 earlyprintk SCIF support.
This makes the early printk support somewhat more flexible, moving the port definition to a config option, and making the port initialization configurable for sh-ipl+g users. At the same time, this allows us to trivially wire up the SH7780 SCIF0, so that's thrown in too more or less for free. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
