4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@xxxxxxxxx>
commit 822969369482166050c5b2f7013501505e025c39 upstream.
The CMD19/CMD14 bus width test has been found to be unreliable in
some cases. It is not essential, so simply remove it.
