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.
