[PATCH v3 1/4] PM: domains: Drop genpd status manipulation for hibernate restore

[Shawn Guo]

The genpd status manipulation for hibernate restore has really never
worked as intended.  For example, if the genpd->status was GENPD_STATE_ON,
the parent domain's `sd_count` must have been increased, so it needs to
be adjusted too.  So drop this status manipulation.
