bcma: invalidate the mapped core over suspend/resume
commit 28e7d218da975f6ae1751e293aed938952c55c98 upstream.
This clears the currently mapped core when suspending, to force
re-mapping after resume. Without that we were touching default core
registers believing some other core is mapped. Such a behaviour
resulted in lockups on some machines.
