Subject: [PATCH] mmc: sdhci-acpi: Reduce Baytrail eMMC/SD/SDIO hangs

Baytrail eMMC/SD/SDIO host controllers have been known to hang. A change to a hardware setting has been found to reduce the occurrence of such hangs. This patch ensures the correct setting.

This patch applies cleanly to v4.4+. It could go to earlier kernels also, so I will send backports to the stable list in due course.
