The patch adds typed PCIe extended-capability lookup to the Rust PCI abstraction and an SR-IOV layout used by the nova-core vGPU boot work. This series is based on v7.3-rc1. That base provides the existing num::casts helpers but not const_as!, so the const narrowing call uses the temporary turbofish form discussed during review. It can be converted as part of the subsequent const_as! migration before the old helper is removed. Changes since v9: - Renamed the internal BAR encoding types to drop the VF-specific prefix and added a TODO to move the common definitions into the PCI core abstraction. (Ilpo, Alexandre) - Rebased onto v7.3-rc1.
