IB/mlx5: Use rdma_for_each_port for port iteration
Instead of open coding the loop for port iteration, use rdma_for_each_port
macro provided by core.
To use such macro, early initialization of phys_port_cnt is needed.
Hence, initialize such constant early enough in the init stage.
Whichever functions are called with port using rdma_for_each_port(),
convert their port type from u8 to unsigned int to match the core API.
