    AMD/Bettong: add function to read board version
    
    Bettong uses 3 GPIO(5-7) pins to identify board.
    The GPIO ports are mapped to MMIO space.
    The GPIO value and board version are mapped as follow:
    GPIO5 GPIO6 GPIO7 Version
      0     0     0      A
      0     0     1      B
      ......
