rk_serial: use kthread_run

Browse Source 
Use kthread_run instead of kthread_create when create kconsole thread.
We should call wake_up_process after kthread_create, otherwise kconsole
will keep in TASK_UNINTERRUPTIBLE state when loglevel=0. Then kconsole
will become hung task, and will trigger hung task timeout.
