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.

That also has nothing to do with this serie. Please send independant patches independantly.
This change required for U-Boot proper to detect mmc0, mmc2 with new CLK, RESET and DM_MMC
No, it will work just fine without that patch, no matter if we're having DM_MMC, RESET or CLK. What we won't have is optimal data rates, but this doesn't really have anything to do with it.
