[PATCH 00/28] cpus: Restrict CPU has_work() handlers to system emulation

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

On user emulation, threads always have work to do, and
CPUClass::has_work() is never called. Restrict it to system
emulation, allowing to simplify a bit and reduce code built
on user emulation.

Based-on: <20250121114056.53949-1-philmd@linaro.org>
 "cpus: Prefer cached CpuClass over CPU_GET_CLASS() macro"
