sunxi: driver refresh for 3.13

 - update gmac / mmc / usb / ahci drivers to follow mainline dev trees
 - add driver for spi
 - update clock support
 - update a31 support
 - move to new DT compats where appropriate
 - re-order patchqueue where needed
 - verified working a20 smp
 - move most DTSes off files/
