[PATCH 28/28] cpus: Remove CPUClass::has_work() handler

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

All handlers have been converted to SysemuCPUOps::has_work().
Remove CPUClass::has_work along with cpu_common_has_work() and
simplify cpu_has_work(), asserting SysemuCPUOps::has_work is
always registered.
