    amdsbwd: always enable watchdog register decoding
    
    This seems to be required even if the watchdog is accessed via the common
    MMIO space.
    
    Tested on:
    - Ryzen 3 3200U APU;
    - Ryzen 7 5800X CPU with X570 chipset.
    
    (cherry picked from commit cca0d3bbd8c9f8b50c6940c33704a6c8c464b68f)
