[PATCH] sh: drop maskpos from make_ipr_irq(), remove duplicate irq definitions 

Clean up some of the subtype IRQ definitions for IPR IRQ, and consolidate the
make_ipr_irq() definitions by dropping maskpos.  SH-4A was the only thing
interested in the maskpos, and this should be handled through INTC2 rather
than IPR.
