omap3: igep3: Fix IGEP module second MMC channel power supply
The second MMC channel (used by the WLAN/BT module) is not linked to power regulator. This causes the WLAN/BT module to fail being detected if CONFIG_REGULATOR_DUMMY is not set. This patch adds the two regulators that actually feed the WLAN/BT module (1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the second channel is properly detected. Also change vmmc1 to use symbolic names instead of direct device reference.
