f30ac0ce34 Blackfin Serial Driver: Use timer to poll CTS PIN instead of workqueue. 
This allows other threads to run when the serial driver polls the CTS
PIN in a loop.

0bcfd70ea1 [Blackfin] serial driver: fix bug - cache the bits of the LSR on systems where the LSR is read-to-clear 
Cache the bits of the LSR on systems where the LSR is read-to-clear
so that we can safely read the LSR in random places.  this fixes
older parts where break/framing/parity/overflow was not being detected
at all in PIO mode, and this fixes newer parts where
break/framing/parity/overflow was being reported all the time
without being cleared.
