Everything is using sparseirq these days, so we have no need to
arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation
likewise has no meaning for us, so that's killed off too. We now depend
on nr_irqs expansion by the generic hardirq layer instead.
It's also worth noting that the majority of boards had completely bogus
values for their nr_irqs relative to their CPU and configurations, so
this ends up correcting behaviour for quite a few platforms.

With some recent tidying of duplicate register definitions the se7206 IRQ
code broke:
arch/sh/boards/mach-se/7206/irq.c: error: 'INTC_ICR' undeclared (first use in this function)
arch/sh/boards/mach-se/7206/irq.c: error: (Each undeclared identifier is reported only once
arch/sh/boards/mach-se/7206/irq.c: error: for each function it appears in.)
Fix it up.

This kills off the hardcoded SH_CLK_MD introduced by the SH-2 boards and
converts over to the mode pin API.

There was a leftover inw() used here that really just wants to be a
__raw_readw() instead. Convert it over.

The PIO trapping was only for MRSHPC and the SMC ethernet. Given that the
SMC ethernet is already properly handled and that nothing is using the
MRSHPC, none of this is needed.

The irq_desc needs to be accessed with irq_to_desc(), this fixes up a
build error with irq_desc being undefined.

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 updates the existing boards that specify the register width through
platform data to use the resource flags instead. This eliminates platform
data completely in most cases, and permits further improvement in the
heartbeat driver as well as shrinking the overall private data size.

This flattens out the board directories in to individual mach groups,
we will use this for getting rid of unneeded directories, simplifying
the build system, and becoming more coherent with the refactored
arch/sh/include topology.
