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 - On production boards, LDO2 and 8 are unused.

LDO2 and LDO8 do not go to any peripheral or connector on the board.
Further, these unused regulators should have been 2.8V for LDO2 and
3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.
