pmdomain: Respect the CPU system wakeup QoS limit for s2idle
A CPU system wakeup QoS limit may have been requested by user space. To
avoid breaking this constraint when entering a low power state during
s2idle through genpd, let's extend the corresponding genpd governor for
CPUs. More precisely, during s2idle let the genpd governor select a
suitable domain idle state, by taking into account the QoS limit.
