ARM: dts: imx6dl-sabreauto: update opp table for auto part
Update i.MX6DL automotive part's opp table according to i.MX6DL automotive datasheet Rev.9, 11/2018, it adds 996MHz set-point support as below: LDO enabled(min value): 996MHz: VDDARM: 1.275V, VDDSOC: 1.175V; 792MHz: VDDARM: 1.150V, VDDSOC: 1.150V; 396MHz: VDDARM: 1.125V, VDDSOC: 1.150V; Adding 25mV to cover board IR drop, for LDO enabled mode of 996MHz, as the max value of LDO output can NOT exceed 1.3V, so 25mV is NOT added for VDDARM.
