sh: intc - primary priority masking fixes
This patch contains various intc fixes for problems reported by
Markus Brunner on the linuxsh-dev mailing list:
http://marc.info/?l=linuxsh-dev&m=118701948224991&w=1
Apart from added comments, the fixes are:
- add intc_set_priority() function prototype to hw_irq.h
- fix off-by-one error in intc_set_priority()
- make sure _INTC_WIDTH() is set for primary priority masking
Big thanks to Markus for finding these problems. Version two fixes
a compile error and an inverted primary check.
