dpaa_eth: add VSP compatibility for eth ports

This patch provides compatibility for the Ethernet driver ports with the VSP
capability. Until now, the FMan ports managed by the Ethernet driver were not
able to properly configure VSP because of the buffer layout of the FMan ports
used.

When VSPs are not enabled, the RX and TX path buffer layout are different, the
Ethernet driver maintains separate buffer layouts for transmission and
reception. When VSPs are enabled on a certain FMan port, the buffer layouts for
Rx and Tx should be the same, the same buffer layout being used inside a
storage profile.

In order to bypass this the VSP capability is disabled on the Tx path by setting
ContextB to 0 in the FQ descriptor of the queues that are transmitting the
frames to the Tx port.
