This adds support for hardware-assisted userspace irq masking for
special priority levels. Due to the SR.IMASK interactivity, only some
platforms implement this in hardware (including but not limited to
SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU
needs to wire this up on its own, for now only SH7786 is wired up as an
example.

Hook up DMAC0 on SH7786.

This plugs in clkdev lookups for the SH7786 clocks and migrates off of
clock string usage for the TMU clocks.

Previously the TMU clocks were aliased to the peripheral clock, so this
gets the driver actually toggling the proper clocks now as well.

Now that dev_name() can be used early, we no longer require a static
string. Kill off all of the superfluous timer names.

The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

This patch breaks out the sh4a scif serial port platform
data from a shared platform device to one platform
device per port. Also, add serial ports to the list of
early platform devices.

All sh4a except SuperH Mobile processors are modified by
this patch.

While at it, sh7757 gets early platform device support.

Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().

This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().

A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

This corrects a race with the PHY RST bit not being set properly if the
PLL status changes right before timeout. This resulted in it potentially
failing even if the device came up in time.

Special thanks to Mr. Juha Leppanen and Iwamatsu-san for reporting this
out and reviewing it.

This adds preliminary support for the SH7786 CPU subtype.

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

More information on this particular CPU subtype is available at:
