Update the size of states_array to avoid overflow for
dev_pdata->voltages[j] and dev_pdata->states[j].
As the size of array is GPIO_REGULATOR_MAX_STATES, the size of
states_array is limited by GPIO_REGULATOR_MAX_STATES * 2 = 4
instead of 8 previously.
The value of the "count" variable is limited by the third parameter of
fdtdec_get_int_array_count.
