at91: Convert remaining boards to new-style UART initialization
Browse files Browse the repository at this point in the history 
Convert the following AT91RM9200-based boards to the new-style UART
initialization:
  - Ajeco 1ARM Single Board Computer
  - Sperry-Sun KAFA board
  - picotux 200

Remove the deprecated at91_init_serial
