regulator: qpnp-regulator: Update FTSMPS voltage ranges to match hardware

Update the FTSMPS voltage ranges so that they accurately reflect
the physical output voltages resulting from set points
programmed on PMIC hardware.

Previous hardware documentation contained these equations:
range == 0: Voutput = setpoint * 5 mV + 80 mV
range == 1: Voutput = setpoint * 10 mV + 160 mV

The actual hardware response is:
range == 0: Voutput = setpoint * 5 mV
range == 1: Voutput = setpoint * 10 mV

Update range data in qpnp-regulator to match the true mapping.
