ar71xx: fix ethernet FIFO state corruption on ar7240
When starting/stopping DMA sometimes the FIFO state gets corrupted,
leading to wildly fluctuating latencies or packet data corruption.
Fix this by issuing a fast MAC reset as soon as the link is detected
as up. Fixes #9689, #9405
SVN-Revision: 27896
