ARM: dts: dra7xx-evm: add evm_3v3_sd regulator
Add a node for evm_3v3_sd using onboard PCF GPIO expander which feeds on to mmc vdd. Update mapping for vmmc-supply and vmmc_aux-supply. evm_3v3_sd supplies to SD card vdd, and ldo1 to sdcard i/o lines. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
