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.

This mostly depends on the board you have. The rootfs could be on the
flash, on nfs or even on a usb stick.

Yeah, could be. It's just that all boards I know of so far have either
SD card or eMMC.
Maybe it's better put in defconfig.

Yes, definitely. The current patch also causes a Kconfig warning when
a user disables CONFIG_MMC, as that a dependency for MMC_SUNXI.

There are tons of other options that users need to select to have
a usable system, no need to treat this one special.
