This patch allows the bcm57xx module to work correctly with failsafe mode.
insmod doesn't return an error when a module loads but doesn't detect a switch.
I added the check_module function to load the module, then make sure
it doesn't just exit immediately. This allows preinit to only attempt to
load the bcm57xx module when switch-robo and switch-adm dont detect a switch.
The activate_gpio parameter to bcm57xx simply instructs the module to attempt
to activate the switch via gpio before probing for the switch.
Tested on wrt350n.
