input: touchscreen: fts: reduce timeout waiting for FIFO flush echo
In some cases, the flushFIFO command waits for 5s for completion,
times out, then repeats the command and wait two more times. This can
result in a total of 15s delay at a time when the touch IC appears to be
unresponsive during suspend, so drastically shorten the echo delay to
50ms per attempt. This does not solve the underlying problem but should
improve the user experience when it does occur.
