clk: ux500: move AB8500 sysclk over to PRCMU clk driver

Browse Source 
The AB8500 sysclk is just another PRCMU-controlled clock, there
is no reason why it should be in the ABx500-controlled part of
the clock implementation. Doing this and the corresponding device
tree changes makes USB work on the Ux500 again.
