[PATCH 04/11] arm64: Introduce Allwinner SoC config option

[Andre Przywara]

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.
Since the MMC driver is quite essential for Linux to be useful, select
it by default.
