[PATCH] hwmon: New f71805f driver

This is my f71805f hardware monitoring driver ported from lm_sensors
to Linux 2.6. This new driver differs from the other hardware monitoring
drivers in that it is implemented as a platform driver. This might not
be optimal yet (we would probably need a generic infrastructure and bus
type for Super-I/O logical devices) but it is certainly much better than
the i2c-isa solution.

Note that this driver requires lm_sensors CVS. I hope to get it
released as 2.10.0 soon.
