ARM: pxa: define clock registers as __iomem
We should not dereference registers as pointers, so use readl/writel
instead for these registers.
The clock registers are accessed in multiple files, so we have to
change them all at once.
I stumbled over these registers while looking at something unrelated.
There are in fact other registers with the same problem, but I did
not try to address those at this point.
