vme: move back to staging

The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of
staging") stating:

    The VME device drivers have not moved out yet due to some API
    questions they are still working through, that should happen soon,
    hopefully.

However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.

drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.
