4k stacks on nommu ends up blowing up with all sorts of interesting
slab corruption. Disable this by default unless BROKEN is also
enabled.

This adds support for the SH7263 (SH-2A) CPU.
This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.
No visibly nasty surprises, yet..

While using separate IRQ stacks can cut down on stack consumption,
many users can also use 4k stacks directly without the additional
need of separate stacks for soft and hardirqs.
With this split, we support the same rationale for 4KSTACKS as
m68knommu, with the IRQSTACKS abstraction as per ppc64.

SH-2 can presently get in to some pretty bogus states, so
we tidy up the dependencies a bit and get it all building
again.
This gets us a bit closer to a functional allyesconfig
and allmodconfig, though there are still a few things to
fix up.

The kgdb thread support is woefully out of date (it predates
the pidhash), and needs a complete rewrite before it's useful
again. Just rip it out entirely.
Updating the unified kgdb stub is a more worthwhile endeavour
for anyone that happens to be interested in this, at present
it's just limping along.

This code has suffered quite a bit of bitrot, do some basic
tidying to get it to a reasonably functional state again.
This gets the basic support and the console working again.
