[PATCH RFC 09/15] ARM: dts: sun6i: sina31s: Switch to mmc3 for onboard eMMC

[Chen-Yu Tsai]

According to Allwinner, only mmc3 supports 8 bit DDR transfers for eMMC.
Switch to mmc3 for the onboard eMMC, and also assign vqmmc for signal
voltage sensing/switching, and "cap-mmc-hw-reset" to denote this
instance can use eMMC hardware reset.
