watchdog: qcom: stop watchdog by default
Prevent the Qualcomm watchdog from autostarting and ensure it's stopped
when the driver probed. In some cases the watchdog is left running by
a previous bootloader stage. Disable autostart so it isn't left running
when we boot into the OS, this behaviour can be changed by enabling
autostart in the board defconfig.
