#1562520 — [PATCH] VME: add again remove entry point

Commit 050c3d52cc7 dropped the remove
entry point. However, vme_bus_remove()
is called when a VME device is removed
from the bus and not when the bus is removed
and it calls the VME device driver's cleanup
function.
Without this function, the remove() in VME
device driver is never called and VME device
drivers cannot be reloaded again.
