[U-Boot] [PATCH 1/2] ARM: dts: imx6q-logicpd: Keep GEN3V3 alive

The schematic shows Gen3V3 is driven by sw2_reg on the pfuze100
PMIC.  Linux doesn't appear to have an issue keeping this rail
up, but U-Boot shuts it down for some reason.

This patch sets 'regulator-always-on' for sw2_reg to keept this
rail powered.
