        src/sys/dev/sdmmc: sdmmc_mem.c

Log Message:
ODROID-C1 has a bug where the card is not power-cycled when the board is
reset. If you had previously switched to 1.8V signaling level, upon reboot
the card will still be in 1.8V mode and you cannot detect it with an S18R
request.

A card in 1.8V mode will report UHS modes though, so if the card reports
SDR50, DDR50, or SDR104 capabilities, and the previous S18R request failed
to switch, use this as an opportunity to re-enable UHS support in the
subsystem and host controller drivers.
