The driver should only use the kernel mapped io address, zr36057_mem, and
not the PCI bus address, zr36057_adr.  Since the latter is only printed out
once, there is no need to save it in the driver data structure.

There was some old code that looked like it was for the Alpha architecture
which would use the PCI bus address.  It probably no longer applies to
modern kernels.
