[PATCH v1 1/2] serial: 8250_port: Remove redundant pm_runtime_mark_last_busy() call

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The pm_runtime_mark_last_busy() call is redundant in the wrapper function
as pm_runtime_put_autosuspend() already calls pm_runtime_mark_last_busy()
internally to update the last access time of the device before queuing
autosuspend.
