dt-bindings: watchdog: qcom-wdt: fix list of MSM timer compatibles

The MSM timer ("qcom,msm-timer") is a bit different timer and watchdog
device than KPSS watchdog.  It has its own generic and specific
compatibles, so fix the list to reflect this.  Adjust the example to
show the newer KPSS watchdog.
