e1000: Fix for 32 bits platforms with 64 bits resources

The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.

This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.

The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.
