To declare that we don't have a PCI bus in the system we do two things: 1. Probe IO ports before enabling access - In case we are using the QEMU ISA-PC machine type, IO probing results in floating bus condition (returning 0xFF values), thus, we know we don't have PCI bus on the system. 2. Allow the user to specify to not use the PCI bus at all in the kernel commandline.
