treewide: Remove redundant

Merge series from Sakari Ailus <sakari.ailus@linux.intel.com>:

Late last year I posted a set to switch to __pm_runtime_mark_last_busy()
and gradually get rid of explicit pm_runtime_mark_last_busy() calls in
drivers, embedding them in the appropriate pm_runtime_*autosuspend*()
calls. The overall feedback I got at the time was that this is an
unnecessary intermediate step, and removing the
pm_runtime_mark_last_busy() calls can be done after adding them to the
relevant Runtime PM autosuspend related functions. The latter part has
been done and is present in Rafael's tree at the moment, also see
