Subject: [PATCH 67/80] usb: 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().

The cover letter of the set can be found here
<URL:https://lore.kernel.org/linux-pm/20250704075225.3212486-1-sakari.ailus@linux.intel.com>.
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:
