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
