MLK-14697 ARM: dts: imx: update the setpoint data of imx6sll

According to the latest datasheet(Rev.0 4/2017), The voltage of
996MHz should be updated to 1.23V. For NXP's Pfuze PMIC chip, the
minimum voltage step is 25mV, we need to set the voltage of 996MHz
to 1.25V. In order to cover board tolerance and IR drop, we add
25mV margin. Then the 996MHz setpoint voltage is 1.275V.
