net: stmmac: multiple queues dt configuration
This patch adds the multiple queues configuration in the Device Tree. It was also created a set of structures to keep the RX and TX queues configurations to be used in the driver. Signed-off-by: Joao Pinto <jpinto@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
