commit 99d570da309813f67e9c741edeff55bafc6c1d5e upstream.

Enable CONFIG_MMC_SDHCI_IO_ACCESSORS so that SDHC controller specific
register read and write APIs, if registered, can be used.

We got a report [1] that a specific platform (ipq806x) fails to build,
after the following commit in the v4.14 stable kernel:
4abb6960f61c ("mmc: sdhci-msm: Disable CDR function on TX")

Let's pick this patch into v4.14.y to automagically select this Kconfig
dependency for platforms which have enabled the driver, but not the
accessors in their kernel config.
