Dong Aisheng e51534c806 mmc: core: fix using wrong io voltage if mmc_select_hs200 fails 
Currently MMC core will keep going if HS200/HS timing switch failed
with -EBADMSG error by the assumption that the old timing is still valid.

However, for mmc_select_hs200 case, the signal voltage may have already
been switched. If the timing switch failed, we should fall back to
the old voltage in case the card is continue run with legacy timing.

If fall back signal voltage failed, we explicitly report an EIO error
to force retry during the next power cycle.
