Pci driver can not handle multiple root complex system

Hi all,

I just found out current Genode pci driver does not support a system with multiple root complexes.

More specifically, in the bus_valid() function, it only scans all the devices under the first root complex (starting from bus number 0).  As a result, other devices under different root complexes are considered INVALID, thus will be skipped by pci driver code.

Maybe a simple patch will fix the problem.

Best regards,
