The PMCAT location has conveniently moved on newer SH-X3 parts, special
case this for now with a note. This will probably want to be redone in a
less visually offensive way when/if more information becomes available.

SH7786 is the big user for subgroup splitting, mostly for the PCIe block,
but those will follow later. For now we simply split up SCIF1, as used by
the serial console on SDK7786 and others.

The gpio sysfs support needs to get at these later, so drop the

Some controllers will need to be initialized lazily due to pinmux
constraints, while others may simply have no need to be brought online if
there are no backing devices for them attached. In this case it's still
necessary to be able to reserve their hardware vector map before dynamic
IRQs get a hold of them.

The SH-X3 proto CPU has all of the external IRQ and IRL pins muxed, make
sure that we're able to grab them before attempting to register their
respective IRQ controllers.

This adds in support for GPIO/pinmux on the SH-X3 proto CPUs. This will
subsequently be used by the x3proto board.

This adds in hardware IRQ auto-distribution support for SH-X3 proto CPUs,

This shuffles some of the shared bits out of the 7786 code and in to a
shared SH-X3 support file. Presently just for userimask, but also a good
place for the IRQ balancing wrappers.

Move the CPG helpers to drivers/sh/clk-cpg.c V2.
This to allow SH-Mobile ARM to share the code with
SH. All functions except the legacy CPG stuff is moved.

This patch is V2 of the SH clock framework move from
arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All
code except the following functions are moved:
clk_init(), clk_get() and clk_put().
The init function is still kept in clock.c since it
depends on the SH-specific machvec implementation.
The symbols clk_get() and clk_put() already exist in
the common ARM clkdev code, those symbols are left in
the SH tree to avoid duplicating them for SH-Mobile ARM.
