arm: mach-kirkwood: use IOMEM() for base address definitions

We now define all virtual base address constants using IOMEM() so that
those are naturally typed as void __iomem pointers, and we do the
necessary adjustements in the mach-kirkwood code.

Note that we introduce a few temporary additional "unsigned long"
casts when calling into plat-orion functions. Those are removed by
followup patches converting plat-orion functions to void __iomem
pointers as well.
