arm64: Introduce Allwinner SoC config option
To prepare for supporting the Allwinner A64 SoC, introduce a config
option to allow compiling Allwinner (aka. sunxi) specific drivers
for ARM64.
This patch just defines the ARCH_SUNXI symbol to allow Allwinner
specific drivers to be selected during kernel configuration.
