ibm: tacoma: Fix I2C hwmon conf files paths

The AST2600 device tree paths for the I2C buses are different than on
the AST2500, so add a new set of hwmon conf files for the tacoma system
that are the same as witherspoon but just in a different directory.

Stopped doing CHIPS_append in the recipe since witherspoon-tacoma
inherits from witherspoon it was getting all of witherspoon's conf files
as well.
