Generalize this
Change the name prcm_config.
Possiblly pass in an enum for supported clk.

Setting the omap clk is not this simple.
It is dependent on at least the input frequency.
I do not see where this is checked here.
You should rethink how this is being done.

Move this to the beagle board dir.
