Subject: [PATCH 7/9] ARM: dts: omap5-uevm: update LDO6 voltage to 1.2V

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.

LDO6 supplies the board specified VDDS_1V2_WKUP supply going to
ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply
1.2V instead of 1.5V.
