Since sci_rxd_in() is used by SCI only, clean up
the header file by killing off code dealing with
SCIF ports and their register definitions.

Also introduce a default sci_rxd_in() function
which can be shared by all SCIF-only processors.

ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard
API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.

The sh-sci code conditionalized the clock framework support in order to
give the other platforms a chance to catch up. sh64 supported this some
time ago and the forthcoming ARM changes handle this as well, this leaves
h8300 as the odd one out. H8300 has had since 2.5 to merge it's sh-sci
support upstream, and has yet to do so. At this point I will no longer be
holding back the driver to support an unreponsive architecture, 7 years
is quite enough of a grace period. Support is easily implemented on the
architecture if and when it ever decides to merge its changes upstream.

While this is a dual-core CPU, only UP is supported for now. L2 cache
support is likewise not yet implemented.

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.

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.
