Subject: [PATCH v2 3/3] staging: vme: "drivers/staging/vme" tree cleanup

In <db3b9e990e75> ("Staging: VME: move VME drivers out of staging") the
vme code, board and bridge drivers were moved out of the staging tree,
remaining only the VME user device driver.

Since this driver is the only one remaining in staging, such multi-level
struct confuses more than helps. The current structure is as follows:

- drivers/staging/vme/
                      +Makefile
                      +devices/
                               +Kconfig
                               +Makefile
                               +vme_user.c
                               +vme_user.h

The root Makefile has the only function of calling the other Makefile
into the devices/ subdirectory. This latter only compiles the vme_user
driver, since there is no other.

This patch allows a more straightforward understanding of this driver's
contents by removing the unnecessary Makefile from the 'vme/' subdir,
moving the contents of 'vme/devices' straight into 'vme/', and renaming
'vme/' to 'vme_user' (the driver name). It also adjusts the Kconfig and
the Makefile from drivers/staging to properly reflect the new structure.

CHANGELOG
v2:
- Added this patch to the patchset
