IB/mlx5: Add support for NDR link speed

[ Upstream commit f946e45f ]

The IBTA specification has new speed - NDR. That speed supports signaling
rate of 100Gb. mlx5 IB driver translates link modes reported by ConnectX
device to IB speed and width. Added translation of new 100Gb, 200Gb and
400Gb link modes to NDR IB type and width of x1, x2 or x4 respectively.
