Use standard dynamic sysfs callbacks instead of macro-generated
functions. This makes the code more readable, and the binary smaller
(by about 34%).
As a side note, another benefit of this type of cleanup is that they
shrink the build time. For example, this cleanup saves about 29% of
the lm80 driver build time.

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.)

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.

The only thing left in i2c-sensor.h are module parameter definition
macros. It's only an extension of what i2c.h offers, and this extension
is not sensors-specific. As a matter of fact, a few non-sensors drivers
use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h
altogether.
