[MIPS] Misc fixes for plat_irq_dispatch functions
o adds missing ST0_IM masks, which caused the logging of valid interrupts
as spurious
o stops pnx8550 to log every interrupt as spurious
o adds cause register masks for ip22/ip32, which caused handling of masked
interrupts
o removes some superfluous parentheses in the SNI interrupt code
