[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)

Browse Source 
Kill normal_isa in header files, documentation and all chip drivers, as
it is no more used.

normal_i2c could be renamed to normal, but I decided not to do so at the
moment, so as to limit the number of changes. This might be done later
as part of the i2c_probe/i2c_detect merge.

If you write a `sensors' driver, you use a slightly different interface.

use a enum of chip types. Don't forget to include `sensors.h'.
