hw/timer/xilinx_timer.c: Switch to transaction-based ptimer API
Switch the xilinx_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.
