cpuidle: psci: Activate GENPD_FLAG_ACTIVE_WAKEUP with OSI
Set GENPD_FLAG_ACTIVE_WAKEUP flag for domain psci cpuidle when OSI
is activated, then when a device is set as the wake-up source using
device_set_wakeup_path, the PSCI power domain could be retained to allow
so that the associated device can wake up the system.
With this flag, for S2IDLE system-wide suspend, the wake-up path is
managed in each device driver and is tested in the power framework:
a PSCI domain is only turned off when GENPD_FLAG_ACTIVE_WAKEUP is enabled
and the associated device is not in the wake-up path, so PSCI CPUIdle
selects the lowest level in the PSCI topology according to the wake-up
path.
This patch is a preliminary step to support PSCI OSI on the STM32MP25
platform with the D1 domain (power-domain-cluster) for the A35 cortex
cluster and for the associated peripherals including EXTI1 which manages
the wake-up interrupts for domain D1.
