libmlx5: sync PCI device allowlist with mlx5_core_pci_table

Browse Source 
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.
