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.
