[ARM] 3022/1: Missing peripheral devices memory mapping definition fo…

…r IXP46X processor

Patch from Kenneth Tan

Defining IXP46X peripheral devices memory mapping definitions that have
been missed out:
o Peripheral virtual base address is being adjusted to allow more headroom to add extra peripheral device addresses
o Peripheral size is being increased to address the above needs
o Virtual address of expansion bus and PCI configuration register needs to be adjusted as new peripheral device memory space is overlapping with their virtual address space
