net/mlx5: Introduce generic helper for PF SFs info

Browse Source 
Introduce mlx5_esw_sf_max_pf_functions() that queries a PF's max_num_sf
and sf_base_id using mlx5_vport_get_other_func_general_cap(), which
supports both function_id and vhca_id based addressing.

Refactor mlx5_esw_sf_max_hpf_functions() into a thin wrapper that adds
the host PF precondition checks and calls the new generic helper. Remove
mlx5_query_hca_cap_host_pf() as it is not used anymore.

This prepares for querying SFs info of Satellite PFs.
