serial: bfin_5xx: add missing spin_lock init
commit 9c529a3d76dffae943868ebad07b042d15764712 upstream.
The Blackfin serial driver never initialized the spin_lock that is part of
the serial core structure, but we never noticed because spin_lock's are
rarely enabled on UP systems. Yeah lockdep and friends.
