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. I just want to avoid people getting
disappointed when enabling Allwinner support and not being able to use
it properly. You know that arm64 has only _one_ defconfig to rule them
all, so compiling a special kernel with magic config options is not the
usual drill for arm64 - for good reasons.

I don't see why MMC support should be essential for A64 SoC.

So I guess I put it in defconfig then, together with the patch to
actually enable Allwinner support by default, which I forgot in this series.

Cheers,
Andre.
