[PATCH] arm64: allwinner: dts: h6: fix Pine H64 MMC bus width

[Icenowy Zheng]

Currently the enabled MMC controllers on Pine H64 do not have bus-width
set, which make them fall back to 1-bit mode and become quite slow.

Fix this by add the corresponding bus-width properties.

BTW why didn't I see it in next-20180820?

It's 3 weeks later, and you didn't say that the patch is queued for
another version.

This has been merged to a fix branch we'll send for 4.19 once rc1 is
