arm64: dts: mediatek: asurada: Enable MMC

Enable both MMC controllers present on Asurada. MMC0 is for
non-removable internal memory, while MMC1 is an SD card slot. MMC1 isn't
used on all machines, but in those cases the CD interrupt is never
triggered and thus it is basically as if it was disabled.
