commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7 (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes) introduced regulator entries for OMAP5uEVM. However, The regulator information is based on an older temporary pre-production board variant and does not reflect production board 750-2628-XXX boards. LDO9 supplies the board specified vdds_sdcard supply going within SoC specification of 1.8V or 3.0V. Further the supply is controlled by switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled on need basis.
