omap3evm: Initialize vmmc and vmmc_aux regulators
Initialize vmmc and vmmc_aux regulators
Note that the omap3evm_twldata.vmmc1 and omap3evm_twldata.vsim
are set in omap3_evm_i2c_init() to avoid a merge conflict
with the MFD tree. These will be initialized in omap3evm_i2c_boardinfo
as a fix later on.
