    libmlx5: sync PCI device allowlist with mlx5_core_pci_table
    
    Userspace mlx5_driver_init() only attached when vendor/device matched
    hca_table, while the kernel already probed additional Mellanox PCI IDs
    That mismatch prevented libibverbs from loading the mlx5 provider on
    those HCAs.
    
    Extend hca_table to mirror mlx5_core_pci_table and add cross-references
    so future kernel ID additions are paired with a userspace update.
