    qoriq: enable Book-E Watchdog Timer
    
    Enable PowerPC Book-E Watchdog Timer support. Having this enabled
    in-kernel will result in procd starting it during boot.
    
    This effectively solves the problem of the WDT in the Winbond W83793 chip
    potentially resetting the system during sysupgrade, which could result
    in an unbootable device. While the driver is modular, resulting in procd
    not starting the WDT during boot (because that happens before kmod
    load), the WDT handover during sysupgrade results in the WDT being
    started. This normally shouldn't be a problem, but the W83793 WDT does
    not like procd's defaults, nor the handover happening during sysupgrade.
