rfnoc: dma_fifo: Added a more robust flush mechanism
- The flushing mechanism now looks similar to that in noc_shell
- Make use of new flush bit in FIFO control register
- Restrict using the clear bit only after flushing to ensure no
partial packets are introduced in the stream. (clear immediately
empties out FIFOs)
- Changes are backwards compatible with older FPGAs
