[PATCH 04/13] arm64: dts: rockchip: rk3308-rock-pi-s: Add sdmmc related properties

Add cap-mmc-highspeed to allow use of high speed MMC mode using an eMMC
to uSD board. Use disable-wp to signal that no physical write-protect
line is present. Also add vcc_io used for card and IO line power as
vmmc-supply.
