e1000e: remove inapplicable test for ioport
There are currently no devices supported by the e1000e driver which need ioport resources, remove the test for it and all unnecessary code associated with it (struct e1000_adapter elements, local variables, etc.) Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
