[XenPPC] [rfc] Serial discovery.

Right now our serial device is assumed to be hanging off an ISA bus (hardcoded address) at an offset (also hardcoded). Neglecting the IOMMU, the only devices that we are interested is console. Right now we are restricting console to a UART, and have no plans to support a framebuffer,ps/2,ADB,USB stuff tho it is possible (except for USB :)).

Anyway, rather defining a bus+offset I think we should just keep an absolute address for the UART.

thoughts?
