tty: move tty_port workqueue to be a kthread
This makes each tty_port have their own kthread, hopefully allowing them
a bit more freedom in scheduling when they reveive data.
Based on a patch from Philip Cuadra <philipcuadra@google.com>
Based on a patch from Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Bug: 36106419
Test: run Bluetooth audio, ensure separate tty thread is created.
