The built-in watchdog is redundant when the device has an external
GPIO based hardware watchdog. And there is a conflict that both of
them will attempt to register the same device entry in sysfs. This
resulted in the built-in watchdog being unable to be activated.
This patch explicitly disables the built-in watchdog for devices
that use GPIO watchdog to fix the error:
[ 1.779206] ath79-wdt 18060008.wdt: unable to register misc device, err=-16
[ 1.786355] ath79-wdt: probe of 18060008.wdt failed with error -16

ath79 uses the generic-ehci driver, which does not support regulators
using vbus-supply.
dr_mode is also not useful as the driver does not support multiple
modes.
