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.

In reply to#1195800
MMC1 supports SDR104 and MMC2 supports HS200 both of which requires
192MHz clock. Set the maximum operating clock frequency to 192 MHz.
