Hmm, looking at history from git log gives me a hint about that it's
the dts that may have the wrong pinctrl for the pwrseq node used for
eMMC.
commit 225da7e65a03 ("ARM: dts: add eMMC reset line for
exynos4412-odroid-common") was introduced in v4.1, which adds the
pwrseq node containing a pinctrl. However, at that point pinctrl was
not a supported DT binding, thus not used by the mmc core.
It's not until the commit you point to above, for when we start
parsing for pinctrl, via driver core.
So as a test, could you try the patch below, to see if that helps.
