[PATCH] PM / Runtime: honor device autosuspend in pm_generic_runtime_idle()

[Mika Westerberg <mika.westerberg@linux.intel.com>]

If the device is using autosuspend we should honor that and call
pm_runtime_autosuspend() instead of pm_runtime_suspend(). Failing to do so
causes the device to be suspended immediately even though it expects to be
suspended only when the autosuspend delay is expired.
