  - Don't blindly use the return value of uart_cpu_channel() to calculate
    the address of a channel on a SCC, it returns 0 on failure.
  - Hardcode channel 1 for the keyboard on Z8530, the information present
    in the Open Firmware device tree doesn't allow to determine this via
    uart_cpu_channel(). This makes the keyboard on Ultra 2 basically work.
  - Add and improve comments about uart_cpu_channel() and uart_cpu_getdev_*().
