[U-Boot] [PATCH v3 24/58] arm64: allwinner: dts: h6: fix Pine H64 MMC bus width

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.

Same commit is there in mailing-list, but yet to merge,
