Allwinner sunXi SoCs clock changes

This adds support for the new, more correct clock node naming and gets
the A10 compatibles in line with the rest of the other SoCs. It also
adds support for the USB, GMAC and A31's PLL6 clocks. Some of these
changes also require DT modifications that will be merged via arm-soc.
