maple: remove unneeded maple_bus_uevent() callback.

The driver core recently changed the uevent bus callback to take a const
pointer, and the maple_bus_uevent() was not correctly fixed up. Instead
of fixing the function parameter types, just remove the callback
entirely as it does not do anything, so it is not necessary.
