eth: 8139too: Make 8139TOO_PIO depend on !NO_IOPORT_MAP

Browse source

[ Upstream commit 43adad382e ]

When 8139too is probing and 8139TOO_PIO=y it will call pci_iomap_range()
and from there __pci_ioport_map() for the PCI IO space.
If HAS_IOPORT_MAP=n and NO_GENERIC_PCI_IOPORT_MAP=n, like it is on my
m68k config, __pci_ioport_map() becomes NULL, pci_iomap_range() will
always fail and the driver will complain it couldn't map the PIO space
and return an error.

NO_IOPORT_MAP seems to cover the case where what 8139too is trying
to do cannot ever work so make 8139TOO_PIO depend on being it false
and avoid creating an unusable driver.
