Couple of quick notes, mostly for future work.

Should be fixed to also call clk_prepare (and clk_unprepare after
clk_disable). Could be done in a follow up patch.

Should we fix this driver to use readl/writel instead of the __raw
variants? The memory is properly ioremaped, and to my understanding the
__raw memory accessors should be avoided outside of core code. This
could be done in a follow up patch if you want to keep this patch as
mostly just a move of the code.
