Kernel/PCI: Assign a PCI address in the SysFS PCI device directories

Browse Source 
This is a bug that went unnoticed for a long time, so the exposed values
in SysFS PCI device directories were incorrect because the assigned PCI
address was simply the host bridge always.

Also, the bus typing should really be two hexadecimal digits and not 4
digits.
