After the recent commit to kill off SCI/SCIF special casing SH 7751R
fails to compile with CONFIG_SH_RTS7751R2D set. This is because SCSPTR1
is undefined. Take the value for SCSPTR1 from the SH7751R Group Hardware

Presently this is conditionalized on sh, and disabled for sh64.
Now that SH-5 ties in to the clock framework, the sh64 exception
can be dropped. Additionally, ARM will want to use the same hooks
once SH-Mobile G3 grows clock framework support, so switch these
paths over to HAVE_CLK now.
Once the H8 and ARM sh-sci users hook up HAVE_CLK, the driver can
be switched over to having an outright dependency on it and the
ifdefs can go away.

Presently we don't do much with UPF_IOREMAP other than special case it

Commit c63847a362 ("sh: Add
SCIF2 support for SH7763.") broke build with CONFIG_EARLY_PRINTK
enabled for me (SH7760):

Move the SH7763 definitions out on their own, so they don't create additional
confusion within the SH7760/SH7780/SH7785 block. Restore the deleted
SCFDR definition for these parts.

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.
In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

This patch makes sure the sci serial port driver compiles for sh7708.
The approach taken is to treat the sh7708 as a subset of sh7706, sh7707,
sh7709. sh7708 is very similar to sh7706, sh7707, sh7709, but only
equipped with a single sci port. The platform data in setup-sh770x.c
already limits the number of serial ports for sh7708 to a single one,
so the non-existing scif ports pointed out in sh-sci.h will remain
unused in case of sh7708.

This adds preliminary support for the SH7785-based Highlander board.
Some of the Highlander support code is reordered so that most of it
can be reused directly.
This also plugs in missing SH7785 checks in the places that need it,

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.

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!
