Subject: [PATCH 1/2] arm64: dts: renesas: salvator-xs: Add SD/OE pin properties

Add SD/OE pin properties to the devicetree so that Linux can configure
the pin without relying on the OTP. This matches the register
configuration reported by Geert [1], as well as my inspection of the
schematic (which shows the SD/OE pin permanently tied high).
