The PCF8591 can't be detected, don't even try. There are plenty of
other means to instantiate i2c devices these days.

Register PCF8591 devices as hwmon devices. There's little point in
implementing the standard sysfs interface if we don't register it in
a way libsensors will pick it.

This macro simply declares an enum, so drivers might as well declare
it themselves.

Struct i2c_client_address_data only contains one field at this point,
which makes its usefulness questionable. Get rid of it and pass simple
address lists around instead.

The "kind" parameter always has value -1, and nobody is using it any
longer, so we can remove it.

Directory drivers/i2c/chips is going away, so drivers there must find
new homes. For the pcf8591 driver, the best choice seems to be the
hwmon subsystem. While the Philips PCF8591 device isn't a typical
hardware monitoring chip, its DAC interface is compatible with the
hwmon one, so it fits somewhat.
If a better subsystem is ever created for ADC/DAC chips, the driver
could be moved there.
