sh: modify NR_IRQS from 256 to 512
Newer parts need NR_IRQS > 256, so simply bump this up to 512 across the
board. At this point sparseirq is used unconditionally across all CPUs,
so this introduces minimal overhead.

sh: intc: IRQ auto-distribution support.
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.

sh: Tidy up duplication in irq/swab/timex.h.
The asm-generic versions have some helper definitions that we can use
instead, drop our definitions and use those instead.

sh: Add a NR_IRQS_LEGACY for external IRQ0-7.
This adds a NR_IRQS_LEGACY definition, which will be used by sparse irq.

sh: migrate to arch/sh/include/
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.
Most of the moving about was done with Sam's directions at:
http://marc.info/?l=linux-sh&m=121724823706062&w=2
with subsequent hacking and fixups entirely my fault.
