Emilio López e874a66977 clk: arm: sunxi: Add a new clock driver for sunxi SOCs 
This commit implements the base CPU clocks for sunxi devices. It has
been tested using a slightly modified cpufreq driver from the
linux-sunxi 3.0 tree.

Additionally, document the new bindings introduced by this patch.
