[PATCH 07/11] target/arm: Convert cpu_exec_halt() to transition_halt_to_exec()

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

arm_cpu_exec_halt() now merely checks cpu_has_work() and
conditionally call arm_cpu_transition_halt_to_exec(), which is now
the generic flow in cpu_has_work_after_processing_async_events().

Register the transition_halt_to_exec handler to use the generic
target-agnostic flow and remove the arm_cpu_exec_halt() wrapper.
