Dave Penkler e6ab504633 staging: gpib: Destage gpib
Move the gpib drivers out of staging and into the "real" part of the
kernel.  This entails:

 - Remove the gpib Kconfig menu and Makefile build rule from staging.
 - Remove gpib/uapi from the header file search path in subdir-ccflags
   of the gpib Makefile
 - move the gpib/uapi files to include/uapi/linux
 - Move the gpib tree out of staging to drivers.
 - Remove the word "Linux" from the gpib Kconfig file.
 - Add the gpib Kconfig menu and Makefile build rule to drivers
