hw/timer/mss-timerc: Switch to transaction-based ptimer API
Switch the mss-timer code away from bottom-half based ptimers to the new transaction-based ptimer API. This just requires adding begin/commit calls around the various places that modify the ptimer state, and using the new ptimer_init() function to create the timer.
