Tomasz Bursztyka 655fb9fb2e spi: dw: Fix how internal FIFO is handled
- Refine how DFS is calulated now that it is strictely used to
  manipulate buffer lengths.
- Fix threshold limit
- Tune RX threshold relevantly (reduce it if rx_len is lower than actual)
- Don't push more than available left space in FIFO
- Tune the private structure to lower memory space occupation
