[ARM] omap: fix inappropriate casting in gpio.c
gpio.c wilfully casts physical addresses to void __iomem * and then
fixes them up at runtime using:
bank->base = IO_ADDRESS(bank->base);
where accesses prior to this fixup are via omap_read/omap_write, and
after are by __raw_read/__raw_write. This doesn't lend itself to
static checking, nor to easy understanding of the code.
And so, OMAP_MPUIO_BASE gets to be the right type - integer like since
it's a physical address, not a MMIO pointer.
