This adds support for the GMAC which is use in the A64 and other
Allwinner chips by backporting the changes from the kernel versions
4.13.
Some commits are not backported which are adding support for newly
introduced APIs which are not available in kernel 4.9.

This adds initial support for the A64 Allwinner SoC to LEDE.
It will be build in the new cortexa53 subtarget.
Currently it only supports the pine64 and the image is able to boot on
this SoC.
Camera, Ethernet, HDMI and other parts are currently not working.
