staging: gpib: fix address space mixup

Throughout the gpib drivers, a 'void *' struct member is used in place
of either port numbers or __iomem pointers, which leads to lots of extra
type casts, sparse warnings and less portable code.

Split the struct member in two separate ones with the correct types,
so each driver can pick which one to use.

staging: gpib: fix Makefiles

Having gpib drivers built-in rather than as loadable modules causes
link failure because the drivers are never actually built:

arm-linux-gnueabi-ld: drivers/staging/gpi

staging: gpib: fix Makefiles

Change this to use the correct Makefile syntax, setting either obj-m or obj-y.
