ARM: imx: use __iomem pointers for MMIO

Browse Source 
ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

This found a bug in mach-armadillo5x0.c, where we attempt mmio
on the MXC_CCM_RCSR address that is currently defined to 0xc
and consequently causes an illegal address access.
