ARM: dts: suniv: licheepi-nano: add microSD card

Enable MMC0 and supply the board setting to enable the microSD card slot
on the LicheePi Nano board.
Apart from the always missing write protect switch on microSD slots,
the card-detect pin is not connected to anything, so we use the
broken-cd property.
