Subject: mmc: sdhci-acpi: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers

From: Adrian Hunter <adrian.hunter@intel.com>

commit 265984b36ce82fec67957d452dd2b22e010611e4 upstream.

The CMD19/CMD14 bus width test has been found to be unreliable in
some cases.  It is not essential, so simply remove it.
