Some speeds can be achieved with different number of lanes. For example,
100Gbps can be achieved using two lanes of 50Gbps or four lanes of 25Gbps.
When use different lanes, the port cannot be up. This patch add support
setting lanes and report lanes.

In addition, add a device capability RTE_ETH_DEV_CAPA_SETTING_LANES
When the device does not support it, if a speed supports different
numbers of lanes, the application does not knowe which the lane number
are used by the device.
