Allwinner A13: Add clkng support

Browse Source 
DTS files switch from clocks under /clocks to a ccu (Clock Controller Unit)
a while ago.
Restore A13 functionality by adding a clock driver for it.
Almost every clocks are handled, the missing ones are mostly video related
clocks.

Tested On: A13 Olinuxino
