ARM: pxa: use correct __iomem annotations
This tries to clear up the confusion between integers and iomem pointers
in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
values, in order to let the Linux type checking work correctly. This
patch moves the cast to __iomem as far back as possible, to the place
where the MMIO virtual address windows are defined.
