From: Arnd Bergmann <arnd@arndb.de>
The tnt4882 backend has a rather elabolate way of abstracting the
PIO and MMIO based hardware variants, duplicating the functionality
of ioport_map() in a less portable way.
Change it to use ioport_map() with ioread8()/iowrite8() to do
this more easily.

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.
