MLK-13601-01 ARM: dts: imx: update the setpoint for imx6ull
According to the latest datasheet(Rev.0,09/2016), two new setpoints
are added on i.MX6ULL, 996MHz/1.25V and 792MHz/1.2V. these two setpoints
can only be enabled when LDO is enabled. In order to cover IR drop and
board tolerance, we add a 25mV margin to the voltage.
