[PATCH v2 3/3] PM / Domains: Take wakeup_path_in_band status flag into account

[Ulf Hansson <ulf.hansson@linaro.org>]

Make genpd to take the wakeup_path_in_band status flag into account during
system suspend/resume. More precisely, in case the flag has been set by the
PM core, let's leave the device in full power state and prevent the PM
domain from being powered off.

Changes in v2:
	- Added Geert's Reviewed-by tag.
	- Changed to look at status flag instead of driver flag.
