[ARM] Misc minor interrupt handler cleanups

mach-integrator/pci_v3.c: no need to reference 'irq' arg, its constant

mach-omap1/pm.c: remove extra whitespace

arch/arm/mach-sa1100/ssp.c: remove braces around single C stmt

arch/arm/plat-omap/mcbsp.c:
	- remove pointless casts from void*
	- make longer lines more readable
