[PATCH] ARM: 2658/1: start ixp2000 pci memory resource at 0xe0000000

Patch from Lennert Buytenhek

On the IXDP2800, the bootloader does an awful job of configuring
the PCI bus, so we make linux reconfigure everything.  Having a 1:1
pci:phys address mapping generally simplifies everything, so try to
allocate PCI addresses from the [e0000000..ffffffff] range, which is
the physical address range of the outbound PCI window on the IXP2000.
This does not affect any of the other IXP2000 platforms since they
all use their bootloader's PCI resource assignment.
