Previously, VME bridge support was treated as any other driver (using
module_init() macro), but if VME bridge and vme_user (staging) drivers
were compiled into the kernel, then vme_user would attempt to register
itself before the VME core support had been loaded. This would result
in a kernel panic.
The load order of these built-in drivers is based on the order in which
drivers/staging/vme and driver/vme are compiled.
This patch changes the VME core driver to use the subsys_initcall()
macro which ensures that it is loaded before all other VME drivers
regardless of the order in which they are compiled.

This moves the VME core, VME board drivers, and VME bridge drivers out
of the drivers/staging/vme/ area to drivers/vme/.
The VME device drivers have not moved out yet due to some API questions
they are still working through, that should happen soon, hopefully.
