Subject: [PATCH] pmdomain: arm: scmi_pm_domain: set flag GENPD_FLAG_ACTIVE_WAKEUP

From: Peng Fan <[email protected]>

Set flag GENPD_FLAG_ACTIVE_WAKEUP to scmi genpd, then when a device
is set as wakeup source using device_set_wakeup_enable, the power
domain could be kept on to make sure the device could wakeup the system.

I am fine with the change, wonder if it can be made conditional but I can't
think of a sane way to do so. If Ulf thinks it is harmless to keep it
unconditional on all the domains, then I am fine with that.

I assume Ulf can pick this up directly,
