I think there are a bunch of other boards that need a similar change,
right? There are certainly eMMC devices on other boards, and shouldn't
they be marked with non-removable? In particular, Beaver, Dalmore, and
Pluto, and likely some/all of the Colibri and Avionic Design boards. I
think it should be obvious which SDHCI devices need this, since there
won't be any cd-gpios property and the bus-width will likely be 8.
