mmc: sdhci-pci: Get rid of glk_cqe_enable()
Now that tuning no longer leaves the Buffer Read Enable bit set (refer intel_execute_tuning()), glk_cqe_enable() is no longer needed. Get rid of it. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
