This allows the baud rate for earlyprintk for sh4 without the
standard BIOS to be set via the command line. This uses the same
format as i386 and x86_64, which is:
earlyprintk=serial,ttySC1,38400
The second parameter (ttySC1 above) is usually the console device
name or the io address of the serial port. I allow that to be
specified but ignore it in order to keep the format the same as
i386/x86_64.

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.

Allow multiple early printk consoles via earlyprintk=.
With this change earlyprintk is no longer enabled by default,
it must be specified on the kernel command line. Optionally
with ,keep to prevent unreg by tty_io.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
