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. LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This can only be supplied at 1.5V or 1.8V and we currently supply 2.8V. To prevent any potential device damage risk, use the specified 1.5V-1.8V supply. Remove 'always-on' and 'boot-on' settings here as it is a 'on need' supply to SoC IP and is not enabled by PMIC by default at boot.
