rtase: Implement hardware configuration function

Implement rtase_hw_config to set default hardware settings, including
setting interrupt mitigation, tx/rx DMA burst, interframe gap time,
rx packet filter, near fifo threshold and fill descriptor ring and
tally counter address, and enable flow control. When filling the
rx descriptor ring, the first group of queues needs to be processed
separately because the positions of the first group of queues are not
regular with other subsequent groups. The other queues are all newly
added features, but we want to retain the original design. So they were
not put together.
