Subject: [PATCH 00/14] PM: domains: Various improvements for genpd

The main goal with this series is to improve the way genpd deals with its
governor(s). Especially it turns allocation of governor related data to be
dynamically allocated. It also improves the execution path for runtime-
suspend/resume of devices (attached to a genpd of course) and the similar is
also done for genpd's power-on/off path.

Note that, patch 1->3 have already been sent before in a separate series [1],
but for simplicity I have included them here again.

Tests/reviews are as usual highly appreciated!

Kind regards
Ulf Hansson
