rust: pci: use pci::Vendor instead of bindings::PCI_VENDOR_ID_*

Change Device::vendor_id() to return a Vendor type, and change
DeviceId::from_id() to accept a Vendor type.

Use the new pci::Vendor in the various Rust for Linux callers who were
previously using bindings::PCI_VENDOR_ID_*.

Doing so also allows removing "use kernel::bindings" entirely from most
of the affected files here.

Also, mark vendor_id() as inline.
