Running checkpatch on the core VME code highlights many errors. Fix them.

The DMA resource allocation function is called "vme_request_dma" while
master and slave window allocation functions are called
"vme_master_request" and "vme_slave_request" respectively. Rename
"vme_request_dma" to "vme_dma_request" to fit the pattern.

The vme_lm_free() function is not clearing up the resource created in
vme_lm_request(). In addition vme_lm_free() is void function and is used in
exit/error paths, we should wait for mutex to become free rather than
exiting and not freeing the resource.

Currently the VME callback infrastructure is replicated in each VME driver.
Move this common code into the VME core. Rename functions to fit in better
with naming of other VME functions.

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.

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.
