ARM: dts: sun6i: Add mmc3 pins for 8 bit emmc

Browse source

mmc2 and mmc3 are available on the same pins, with different mux values.
However, only mmc3 supports 8 bit DDR transfer modes.

Since preference for mmc3 over mmc2 is due to DDR transfer modes, just
set the drive strength to 40mA, which is needed for DDR.

This pinmux setting also includes the hardware reset pin for emmc.
