drivers: move the early platform device support to arch/sh

SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.

In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.

Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

sh: Don't set sh-sci port_reg

The driver considers all negative or zero values of the port_reg field
as invalid. The four platforms that set the field to a register address
all use an address higher than 0x7fffffff, which is thus considered by
the driver as invalid. The feature is thus never used, remove it.

The feature could be implemented properly in the future using the
pinctrl and GPIO APIs if desired.

While at it, don't set the field to SCIx_NOT_SUPPORTED (-1) either,
leaving it unset leads to the same result. This will allow removing the
SCIx_NOT_SUPPORTED macro.

serial: sh-sci: Abstract register maps.

This takes a bit of a sledgehammer to the horribly CPU subtype
ifdef-ridden header and abstracts all of the different register layouts
in to distinct types which in turn can be overriden on a per-port basis,
or permitted to default to the map matching the port type at probe time.

In the process this ultimately fixes up inumerable bugs with mismatches
on various CPU types (particularly the legacy ones that were obviously
broken years ago and no one noticed) and provides a more tightly coupled
and consolidated platform for extending and implementing generic
features.

serial: sh-sci: clkdev updates for MSTP gating.

This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.

As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.
