OMAP2+: VC: support PMICs with separate voltage and command registers
The VC layer can support PMICs with separate voltage and command
registers by putting the different registers in the PRM_VC_SMPS_VOL_RA
and PRCM_VC_SMPS_CMD_RA registers respectively.
The PMIC data must supply at least a voltage register address
(volt_reg_addr). The command register address (cmd_reg_addr) is
optional. If the PMIC data does not supply a separate command
register address, the VC will use the voltage register address for both.
