Subject: [PATCH] ARM: dts: microchip: sama5d27_wlsom1_ek: Remove mmc-ddr-3_3v property from sdmmc0 node

On board the sdmmc0 interface is wired to a SD Card socket.
According with mmc-controller bindings, the mmc-ddr-3_3v property
is used for eMMC devices to enable high-speed DDR mode (3.3V I/O).
Remove the mmc-ddr-3_3v property from sdmmc0 node.
