Subject: [PATCH 56/80] pwm: img: Remove redundant pm_runtime_mark_last_busy() calls

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

In brief, this patch depends on PM runtime patches adding marking the last
busy timestamp in autosuspend related functions. The patches are here, on
rc2:
