ARM: dts: imx6dl: correct cpufreq volt/freq table

Currently the cpufreq volt/freq table we used is
for LDO enable mode, according to latest datasheet
Rev. 3, 03/2014, the volt/freq table is as below:

LDO enabled(min value):
996MHz: VDDARM: 1.225V, VDDSOC: 1.150V;
792MHz: VDDARM: 1.150V, VDDSOC: 1.150V;
396MHz: VDDARM: 1.050V, VDDSOC: 1.150V;

LDO bypassed(min value):
996MHz: VDDARM: 1.250V, VDDSOC: 1.150V;
792MHz: VDDARM: 1.150V, VDDSOC: 1.150V;
396MHz: VDDARM: 1.050V, VDDSOC: 1.150V;

Adding 25mV to cover board IR drop, for LDO enabled
mode of 996MHz, VDDARM should be 1.250V, so this
patch updates it.
