spi: hisi-kunpeng: Add timeout warning in FIFO flush function
When flushing the FIFO, the driver waits for the busy flag to clear
with a timeout. Change the loop condition to use pre-decrement (--limit)
instead of post-decrement (limit--) so that warning message can show. Add a
ratelimited warning message to log SPI busy timeout events, aiding in
debugging.
