sunxi: Backport patches needed for A64

This backports multiple patches from kernel 4.10 which are adding
missing support for the A64 and the pine64 board. These are the device
tree files, the pinctlk and the clock driver.

+Subject: arm64: dts: add Pine64 support
+
+The Pine64 is a cost-efficient development board based on the
+Allwinner A64 SoC.
+There are three models: the basic version with Fast Ethernet and
+512 MB of DRAM (Pine64) and two Pine64+ versions, which both
+feature Gigabit Ethernet and additional connectors for touchscreens
+and a camera. Or as my son put it: "Those are smaller and these are
+missing." ;-)
+The two Pine64+ models just differ in the amount of DRAM
+(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
+patches the DT accordingly we just need to provide one DT for the
+Pine64+.
