hw/timer/cmsdk-apb-dualtimer.c: Switch to transaction-based ptimer API
Switch the cmsdk-apb-dualtimer 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.
