From: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx>
Add init data for the LDO regulators used on Beagle boards:
- VMMC1 is the main MMC1 power
- VSIM powers MMC1 too: DAT4-DAT7 pins, for HSMMC cards
- VDAC for S-Video output
Those regulators need to be hooked up to the MMC1 and FB (?) devices
through the regulator framework.
