Subject: mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers
From: Adrian Hunter <adrian.hunter@intel.com>
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.
