This series mainly adds support for mtu3 gadget suspend/resume when
the controller works at device only mode or dual role mode, and also
adds support runtime PM.

v3:
  add Acked-by Rob
  fix use-after-free issue when probe failed
v2:
  Change the comment of cover letter and its title.

  In order to help review, v2 drops the patches about role-switch
  rebuilding which are applied, and the left ones are identical.
