The DMABRG is a special DMA unit within the SH7760 which does data
transfers from main memory to Audio units and USB shared memory.
It has 3 IRQ lines which generate 10 events, which have to be masked
unmasked and acked in a single 32bit register. It works independently
from the tradition SH DMAC, but blocks usage of DMAC channel 0.
This patch adds 2 functions to associate callbacks with DMABRG events
and initialization.

This consolidates the various board heartbeat LED implementations,
used for strobing the load average across a LED bank. Those boards
not implementing a full bank can hook in via the LED class.
We leave the compat hook in the machvec for now until those non-banked
boards are able to migrate to the drivers/leds.

This adds support for a generic push switch framework. Adaptable for
various switches, including GPIO switches and the push switches commonly
found on Renesas debug boards.
This allows switch states to be trivially reported through sysfs.

This adds support for the relatively quirky (ie, not in line with any known
documentation, and amazed it works at all) SuperHyway implementation on
SH4-202. This depends on the earlier SuperHyway patch for multiple block
support and VCR refactoring.

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!
