    created the following warning:
    
    drivers/pinctrl/pinctrl-amd.c: In function 'amd_gpio_dbg_show':
    drivers/pinctrl/pinctrl-amd.c:210:3: warning: 'pin_num' may be used uninitialized in this function [-Wmaybe-uninitialized]
       for (; i < pin_num; i++) {
       ^
    drivers/pinctrl/pinctrl-amd.c:172:21: warning: 'i' may be used uninitialized in this function [-Wmaybe-uninitialized]
      unsigned int bank, i, pin_num;
                         ^
    Fix this by adding a guarding default case for illegal
    bank numbers.
