ARM: fix __io macro for PCMCIA
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.
