libpci: Add new options for pci_fill_info: CLASS_EXT and SUBSYS
This change extends libpci library and allows providers to fill these
informations (Programming interface, Revision id and Subsystem ids) via
native system APIs, which sometimes may differs from what is stored in PCI
config space.
Programming interface is part of 24-bit Device Class number but apparently
libpci exports only high 16-bit of this number via device_class member.
