net/mlx4_core: Add basic support for QP max-rate limiting
Add the low-level device commands and definitions used for QP max-rate limiting.
This is done through the following elements:
- read rate-limit device caps in QUERY_DEV_CAP: number of different
rates and the min/max rates in Kbs/Mbs/Gbs units
- enhance the QP context struct to contain rate limit units and value
- allow to do run time rate-limit setting to QPs through the
update-qp firmware command
- QP rate-limiting is disallowed for VFs
