Turns out the m68k arch already has a CONFIG_VME, so use
CONFIG_VME_BUS instead.
Thanks to Geet Uytterhoeven for pointing this out.

This patch starts the reworking of the vme_ca91cx42.c for the VME core. The
driver seems to have only supported the Universe II for a long time, I have no
hardware to check to see if it would work on the Universe I.
This patch is compile tested with minimal run-time testing. It enables basic
support for slave and master windows and interrupts. The master windows have
undergone basic run testing.

Extend the image and DMA channel resource management methods to control the
location monitor resource. The location monitor should be controlled as it can
only be used at a single location at a time.

The VME core and tsi-148 driver currently use semaphores as mutexes. Switch to proper
mutex implementation.

As identified by Jiri, the VME interrupt free routine removes the service
routine before disabling the interrupt. Re-order operations to be performed in
the reverse of the request routine.

Currently this code doesn't compile, so it is disabled.
That should be fixed up...

This framework aims to colelese, extend and improve the VME Linux
drivers found at vmelinux.org, universe2.sourceforge.net and
openfmi.net/frs/?group_id=144. The last 2 drivers appear to be forks of
the original code found at vmelinux.org though have extended the
codebase.
