sh: intc - rework core code
This patch reworks the intc core, implementing the following features:
- Support dual priority registers - one set and one clear register
- All 8/16/32 bit register combinations are now supported
- Both single mask and single enable bitmap register are supported
- Add code to set interrupt priority
- Speedup sense and priority configuration code
- Allocate data using bootmem, allows intc data structures to be
__initdata
- Save memory - allocated memory footprint is smaller than intc
