wil6210: move eDMA module parameters to debugfs

Move the following eDMA module parameters to debugfs, to minimize
the number of wil6210 module parameters and allow support for
multiple wil6210 devices:
use_compressed_rx_status, rx_status_ring_order, tx_status_ring_order,
rx_buff_id_count

use_enhanced_dma_hw and use_rx_hw_reordering module parameters can
be removed (enabled by default for talyn-mb).
