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. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Tony Lindgren <tony@atomide.com>
