    Fit blackfin uart over sport driver into common uart inftrastructure.  It
    is based on the early platform interfaces to get the platform data early
    when the console is initilized.
    
    1. Enable sport uart driver to change uart baud, data bit, stop bit at
       runtime.  Bind the index of uart device nodes to physical index of
       sports.
    
    2. Move all platform data into arch specific board files.  Register
       and probe platform device data in both early and normal stages.
    
    3. Console is registered in sport uart driver as well.
    
    4. Remove 500 us block waiting in sport tx stop code by putting a
       dummy data into tx fifo to make sure the sport tx stops when all bytes
       are shifted out except for the dummy data.
    
    5. clean up a bit and fix up coding style.
