kind of funny... sdmmc supports sd but not mmc which is slightly
different. I got preliminary support working for rpi compute module
3+, online at https://github.com/echoline/9emmc

it shouldn't be hard to change the relevant ?mmc.c but cinap pointed
out, it doesn't handle cases of bus width, disk speed, or voltage
settings... mmc cards really need all these settings figured out and
implemented from the extended CSD information. it works on these
devices (very slowly) but ymmv and before using it please be sure the
device isn't over-voltaged or something!
