Ulf Hansson 895b66129a PM / Domains: Don't power on at attach for the multi PM domain case
There are no legacy behavior in drivers to consider while attaching a
device to genpd - for the multiple PM domain case.

For that reason, let's instead require the driver to runtime resume the
device, via calling pm_runtime_get_sync() for example, when it needs to
power on the corresponding PM domain.

This allows us to improve the situation during attach. Instead of always
power on the PM domain, which may be unnecessary, let's leave it in its
current state. Additionally, to avoid the PM domain to stay powered on,
let's schedule a power off work.
