MLK-11537 ARM: dts: add setpoint setting for imx6ul-14x14-lpddr2-arm board

On i.MX6UL, the VDD_ARM_IN and VDD_SOC_IN use the same power rail
VDD_ARM_SOC_IN. For imx6ul-14x14-lpddr2-arm2 board, default, we use
ldo-bypass mode and use the external PMIC regulator for cpufreq.so
on this board, should use the setpoint of ldo-bypass mode.
