hwmon: (adc128d818) Use devm_regulator_get_enable_read_voltage()

We can reduce boilerplate code and eliminate the driver remove()
function by using devm_regulator_get_enable_read_voltage().

A new external_vref flag is added since we no longer have the handle
to the regulator to check if it is present.
