Rafael J. Wysocki e00952c790 PM / mfd: intel-lpss: Push system sleep callbacks to late/early stages
Push the system suspend/resume callbacks of intel-lpss to the late
suspend/early resume stages to allow child device callbacks to be
pushed to the late/early stages of suspend/resume too, so as to
make it possible to avoid resuming the children if they are runtime-
suspended during system suspend going forward.
