regulator: lp8788: Implement list_voltage for lp8788_ldo_voltage_fixed_ops
For fixed voltage, we can just set min_uV and use regulator_list_voltage_linear for list_voltage callback. Regulator core will call list_voltage(rdev, 0) if both get_voltage get_voltage_sel are not implemented. Thus we can also remove lp8788_ldo_fixed_get_voltage() function.
