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/ - update defconfig
