[PATCH 2.6] I2C: Separate non-i2c hwmon drivers from i2c-core (6/9)

[Jean Delvare <khali@linux-fr.org>]

Kill all isa-related stuff from i2c_detect, it's not used anymore.

This is one major step in the directiom of merging i2c_probe and
i2c_detect. The last obstacle I can think of is the different way forced
addresses work between sensors and non-sensors i2c drivers. I'll deal
with that in a later patchset.
