Merge Qualcomm MSM timer bindings into watchdog, because the timer
compatibles are already included here and the hardware is quite similar.

While converting the MSM timer bindings, adjust clock-frequency
property to take only one frequency, instead of two, because:
1. DT schema does not allow to frequencies,
2. The Linux timer driver reads only first frequency.
