ENGR00326277-1: imx6: ldo_bypass: fix VDDARM voltage setting violate datasheet
Current only set VDDARM_IN@1.175V/VDDSOC_IN@1.175V before ldo bypass switch.
So untile ldo bypass switch happened, these voltage setting is set in ldo-enable
mode. But in datasheet, we need 1.15V + 125mV = 1.275V for VDDARM_IN. We need
to downgrade cpufreq to 400Mhz and restore after ldo bypass mode switch.
