net: dsa: mxl-gsw1xx: fix .shutdown driver operation

Browse source

The .shutdown operation should call dsa_switch_shutdown() just like
it is done also by the sibling lantiq_gswip driver. Not doing that
results in shutdown or reboot hanging and waiting for the CPU port
becoming free, which introduces a longer delay and a WARNING before
shutdown or reboot in case the driver is built-into the kernel.
Fix this by calling dsa_switch_shutdown() in the driver's shutdown
operation, harmonizing it with what is done in the lantiq_gswip
driver. As a side-effect this now allows to remove the previously
exported gswip_disable_switch() function which no longer got any
users.
