ENGR00320349 cpufreq: imx6: increase SOC/PU voltage for VPU352MHz

For VPU352MHz enabled, SOC/PU voltage can NOT be lower than 1250mV,
as only 396M and 792M setpoint's SOC/PU voltage is lower than
1250mV and we already disable 396M setpoint, so here we just increase
SOC/PU voltage for 792M setpoint when VPU352M is enabled.
