Recent changes on the I2C front have left off-by-one array indexes in
3 hwmon drivers. Fix them.

The low bits of temperature registers are status bits, they must be
masked out before converting the register values to temperatures.

An off-by-one error caused some inputs to not be created by the driver
when they should. TMP421 gets only one input instead of two, TMP422
gets two instead of three, etc. Fix the bug by listing explicitly the
number of inputs each device has.

These macros simply declare an enum, so drivers might as well declare
it themselves. This puts an end to the arbitrary limit of 8 chip types
per i2c driver.

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.

As kind is now hard-coded to -1, there is room for code clean-ups.

Add support for Texas Instruments TMP421/422/423 temperature sensor IC.
TI's TMP421/422/423 are I2C temperature sensor chips. These chips are
similar to TI's TMP401/411 chips, but with reduced functionality (only
temperature measurement). The chips have one local sensor and up to
three (TMP423) remote sensors.
