Misc updates from mlx5-next branch:
1) Add the required HW definitions and structures for upcoming TLS
support.
2) Add support for MCQI and MCQS hardware registers for fw version query.
3) Added hardware bits and structures definitions for sub-functions
4) Small code cleanup and improvement for PF pci driver.
5) Bluefield (ECPF) updates and refactoring for better E-Switch
management on ECPF embedded CPU NIC:
5.1) Consolidate querying eswitch number of VFs
5.2) Register event handler at the correct E-Switch init stage
5.3) Setup PF's inline mode and vlan pop when the ECPF is the
E-Swtich manager ( the host PF is basically a VF ).
5.4) Handle Vport UC address changes in switchdev mode.
6) Cleanup the rep and netdev reference when unloading IB rep.
