net/mlx4_core: Port aggregation low level interface

Implement the hardware interface required for port aggregation.

1. Disable RX port check on receive - don't perform a validity check
that matches to QP's port and the port where the packet is received.

2. Virtual to physical port remap - configure virtual to physical port
mapping. Port remap capability for virtual functions.
