Now .suspend/resume_noirq() callbacks will not be called during
system wide suspend/resume for devices which belongs to some GPD.
It seems, that this change was accidently introduced by
commit d23b9b00cdde ("PM / Domains: Rework system suspend callback
routines (v2)").
This patch restores calling of .suspend/resume_noirq() callbacks
for devices from GPD during system wide suspend/resume.
