ARM: dts: imx6sx-sdb: Add 198MHz operational point
[ Upstream commit 1dd58e12dfd037edfa75825bb719031dec822a73 ] imx6sx-sdb has custom operating points entries because it has one power supply that drives both VDDARM_IN and VDDSOC_IN. As per the MX6UL datasheet we have the following minimum voltages for 198 MHz operation (after adding the 25mV margin value): VDDARM_IN = 0.975 V VDDSOC_IN = 1.175 V So use 1.175V for the 198MHz operation.
