So, PERIPH_BASE is also an iomem cookie, not a physical address, so it
too should be void __iomem *.

Hence:

> +#define PERIPH_BASE            0xF8000000

should be:

#define PERIPH_BASE            IOMEM(0xF8000000)

But then in a different patch you do:
+               .virtual        = TTC0_BASE,
+               .pfn            = __phys_to_pfn(TTC0_BASE),

So it's also used as a physical address.  Yuck.
