This patch converts the drivers in drivers/i2c/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

Hmm, on second thought...
I'm not going to apply the i2c-smbus patch. This is a special module,
it isn't a device driver per se. It happens that right now the only
SMBus extension supported by the i2c-smbus module is SMBus Alert and
it happens that this is implemented as an i2c_driver, but as we add
support for more SMBus extensions to that driver, the init and exit
functions will likely become more complex, and then we'd have to move
away from module_i2c_driver(). So I'd rather not use it to start with.
I am taking the drivers/i2c/muxes/pca954*.c parts though.
