[RFC PATCH 5/5] arm64: dts: sunxi: add MMC nodes to Pine64 and BPi-M64 .dts

[Andre Przywara <andre.przywara-5wv7dgnIgG8@public.gmane.org>]

Those two boards connect a microSD card slot to the MMC0 controller.
Add the dummy regulator and enable MMC0 to allow accessing the SD card.

The BananaPi M64 has an on-board eMMC chip connected to the MMC2
controller, but the existing MMC driver does not support this properly
yet, so keep this one disabled for now.
