twl: beagle regulator updates

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.
