[PATCH 26.07 2/5] net/mlx5: store port VHCA ID

[Dariusz Sosnowski <dsosnowski@nvidia.com>]

Save VHCA ID (if available) of each mlx5 port and
of E-Switch Manager, and update port info cache
(mlx5_flow_hw_port_infos array) used for translating
DPDK port ID into HW matching value and mask,
when matching on source vport.

This data will be later used to implement source vport matching
without E-Switch vport metadata enabled.
