mx6: soc: Update the comments of set_ldo_voltage()
Commit 3d622b78 (mx6: soc: Introduce set_ldo_voltage()) introduces set_ldo_voltage() function that can be used to set the voltages of any of the three LDO regulators controlled by the PMU_REG_CORE register. Prior to this commit there was a single set_vddsoc() which only configured the VDDSOC regulator. Update the comments to align with the new set_ldo_voltage() implementation. Acked-by: Jason Liu <r64343@freescale.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> (cherry picked from commit 157f45da91b306d71dbf3a51325352dc11bf16d1)
