sh: intc - shared IPR and INTC2 controller
This is the second version of the shared interrupt controller patch
for the sh architecture, fixing up handling of intc_reg_fns[].
The three main advantages with this controller over the existing
ones are:
- Both priority (ipr) and bitmap (intc2) registers are
supported
- External pin sense configuration is supported, ie edge
vs level triggered
- CPU/Board specific code maps 1:1 with datasheet for
easy verification
This controller can easily coexist with the current IPR and INTC2
controllers, but the idea is that CPUs/Boards should be moved over
to this controller over time so we have a single code base to
maintain.
