Some of the windfarm sensor modules can initialize on old machines that
don't have full windfarm support like non-dual core desktop G5s.
Unfortunately, by doing so, they would trigger a bug in their matching
algorithm causing them to attach to the wrong bus, thus triggering
issues with the i2c core and breaking the thermal driver.
This patch fixes the probing issue (so that they will work when a
windfarm port is done to these machines) and also prevents for now
windfarm to load at all on these machines that still use therm_pm72 to
avoid wasting resources.

This is the continuation of the previous patch. This one removes the old
PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them
both with a single stub driver that uses the new PowerMac low i2c layer.
Now that i2c-keywest is gone, the low-i2c code is extended to support
interrupt driver transfers. All i2c busses now appear as platform
devices. Compatibility with existing drivers should be maintained as the
i2c bus names have been kept identical, except for the SMU bus but in
that later case, all users has been fixed.
With that patch added, matching a device node to an i2c_adapter becomes
trivial.

processing done
therm_pm72.c and windfarm_lm75_sensor.c both store the return from
i2c_add_driver() but do no further processing on the result. Simply return
what i2c_add_driver() did, instead.

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers. This patch catches all of the
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)

We should use the i2c_driver.driver's .name and .owner fields
instead of the i2c_driver's ones.
This patch updates the drivers for macintosh.

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.

This adds a new thermal control framework for PowerMac, along with the
implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and
PowerMac9,1 (latest single CPU desktop). In the future, I expect to move
the older G5 thermal control to the new framework as well.
