(6/6) bcm57xx: package

This is the bcm57xx package.  I have tested default vlan functions,
but I dont have the equipment to test more advanced setups.  The default
vlan setup seems to be working fine.  I also added the activate_gpio
parameter which will make the driver activate the switch via gpio before
probing for it.

I'm not sure which method is best for autoload.  For the wrt350n, I
need the activate_gpio parameter.  But its probably not a good idea
to add that to the autoload file.  On a system without a bcm57xx switch,
isn't it a bad idea to mess with the gpios looking for the switch? Ideally,
wouldn't it be best to load the bcm57xx module from broadcom-diag, after
it has determined which router its on?  I tried using 'request_module' from
there, but had no success.  For now, I am relying on preinit to load
the bcm57xx module with activate_gpio param, after it has failed to load
switch_robo and switch_adm.
