net/mlx5: IFC updates for SF max IO EQs

Browse Source 
Expose a new cap sf_eq_usage. The vhca_resource_manager can write this
cap, indicating the SF driver should use max_num_eqs_24b to determine
how many EQs to use.

Will be used in the next patch, to indicate to the SF driver from the PF
that the user has set the max io eqs via devlink. So the SF driver can
later query the proper max eq value from the new cap.

devlink port function set pci/0000:08:00.0/32768 max_io_eqs 32
