rust: pci: provide access to PCI Class and Class-related items

Browse source

Allow callers to write Class::STORAGE_SCSI instead of
bindings::PCI_CLASS_STORAGE_SCSI, for example.

New APIs:
    Class::STORAGE_SCSI, Class::NETWORK_ETHERNET, etc.
    Class::from_raw() -- Only callable from pci module.
    Class::as_raw()
    ClassMask: Full, ClassSubclass
    Device::pci_class()
