The conversion from IPR-IRQ to IRQ-chip resulted in the
ipr data being allocated in a local variable in
make_ipr_irq - breaking anything using IPR interrupts.
This changes all of the callers of make_ipr_irq to
allocate a static structure containing the IPR data which
is then passed to make_ipr_irq. This removes the need for
make_ipr_irq to allocate any additional space for the IPR
information.

Currently the INTC2 code contains a fixed IRQ table that it
iterates through to set the handler type, we move this in to
the CPU subtype setup code instead and allow for submitting
the table that way.
This drops the ST40 tables, as nothing has been happening
with those processors, while converting the only existing
users to use the new table directly (SH7760 and SH7780).

The driver that these were using never made it in to
drivers/ide, so kill off the rest of the cruft. These
will have to be reworked for board-specific platform
devices through libata when they're added back through
the setup code.

This enables support for 4K stacks on SH.
Currently this depends on DEBUG_KERNEL, but likely all boards
will switch to this as the default in the future.

This adds support for the aforementioned CPU subtypes, and cleans
up some build issues encountered as a result.

Clean up some of the subtype IRQ definitions for IPR IRQ, and consolidate the
make_ipr_irq() definitions by dropping maskpos. SH-4A was the only thing
interested in the maskpos, and this should be handled through INTC2 rather
than IPR.

This moves the various IRQ controller drivers into a new subdirectory, and
also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780
interrupts, rather than just ST-40.
The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as
new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are
plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

The function prototype for handle_IRQ_event() in a few architctures is not
needed because they use GENERIC_HARDIRQ.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
