Bug description:
  [Impact]
  On some platforms the touchpad relies on pinctrl devices to provide GPIO 
interrupt, but in 3.19.0 pinctrl-cherryview doesn't support suspend well and 
will lose the config after suspend/resume, then touchpad can't be used.

  [Fix]
  There's a commit in 4.0-rc1 to add suspend/resume for pinctrl-cherryview:

  commit 9eb457b547cc731bc2fc251bd79891a60c64fc3e

      pinctrl: cherryview: Save and restore pin configs over system sle

  which can be clean cherry-picked

  3.19.0-33 -> failed
  4.2-> passed
  4.0, 4.1 -> Can't suspend due to graphic driver failed so can't use to test
  3.19.0-33 + patched module -> passed
