net/mlx5: Add MCC (Management Component Control) register definitions

MCC (Management Component Control) allows to control a firmware
component update.

MCDA (Management Component Data Access) allows to read and write
a firmware component.

MCQI (Management Component Query Information) allows to query
information about firmware components.
