This patch converts the remaining sh7724 clocks
to use clkdev for lookup. The now unused name
and id from struct clk are also removed.

This wires up CPU hotplug for SH-X3 SMP CPUs. Presently only secondary
cores can be hotplugged given that the boot CPU has to contend with the
broadcast timer. When real local timers are implemented this restriction
can be lifted.

This implements support for hardware-managed IRQ balancing as implemented
by SH-X3 cores (presently only hooked up for SH7786, but can probably be
carried over to other SH-X3 cores, too).

CPUs need to specify their distribution register along with the mask
definitions, as these follow the same format. Peripheral IRQs that don't
opt out of balancing will be automatically distributed at the whim of the
hardware block, while each CPU needs to verify whether it is handling the
IRQ or not, especially before clearing the mask.

Make sure that the timer IRQs and IPIs aren't enabled for IRQ balancing.
IPIs are disabled as a result of being percpu while the timers simply

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.

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.
