When the tty layer requests the uart to throttle, the current code executing in msm_serial will trigger "Bad mode in Error Handler" and generate an invalid stack frame in pstore before rebooting (that is if pstore is indeed configured: otherwise the user shall just notice a reboot with no further information dumped to the console). This patch replaces the PIO byte accessor with the word accessor already used in PIO mode.

AutoReporter is going away; recent versions of sphinx emit a warning like: Documentation/sphinx/kerneldoc.py:125: RemovedInSphinx20Warning: AutodocReporter is now deprecated. Use sphinx.util.docutils.switch_source_input() instead. Make the switch. But switch_source_input() only showed up in 1.7, so we have to do ugly version checks to keep things working in older versions.
