[PATCH v3 0/3] rust, nova-core: PCI Class, Vendor support

[John Hubbard <jhubbard@nvidia.com>]

Changes since v2:

* Applied changes from Danilo's and Alex's review (thanks!):

    * Moved everything possible out of the new define_all_pci_classes!()
      and define_all_pci_vendors!() macros.
    * Used "impl TryFrom<u32> for Class/Vendor", instead of .from_u32().
    * Made the new DeviceId methods infallible.
    * Upgraded DeviceId::from_id() to accept a Vendor struct.

* Changed the names to be a little clearer:
    * class_code_raw() --> pci_class_code_raw()
    * class_enum() --> pci_class()

* Added doctests for the items that are not yet used in real drivers.

v2 is here:

Changes since v1:

1) Use the pci_device_table for filtering, instead of open-coding
   filters in the .probe() callback.

2) Add PCI Class (class, subclass, implementation) and PCI Vendor to
   Rust for Linux.

3) Rebased onto the latest nova-next branch, which is here:
    https://gitlab.freedesktop.org/drm/nova.git

v1 is here:
