[PATCH v3 03/10] arm64: Introduce Allwinner SoC config option

To prepare for the Allwinner A64 SoC support, introduce a config
option to allow compiling Allwinner (aka. sunxi) specific drivers
for the arm64 architecture as well.
This patch just defines the ARCH_SUNXI symbol to allow Allwinner
specific drivers to be selected during kernel configuration.
