regulator: pm8008: fix probe failure due to negative voltage selector
In the current design, the `pm8008_regulator_get_voltage_sel()` callback
can return a negative value if the raw voltage value is read as 0 uV from
the PMIC HW register. This can cause the probe to fail when the
`machine_constraints_voltage()` check is called during the regulator
registration flow.
Fix this by using the helper `regulator_map_voltage_linear_range()` to
convert the raw value to a voltage selector inside the mentioned get
voltage selector function. This ensures that the value returned is always
within the defined range.
