Subject: [PATCH] mmc: host: tmio: fill in response from auto cmd12

After we received the dataend interrupt, R1 response register carries
the value from the automatically generated stop command. Report that
info back to the MMC block layer, so we will be notified in case of e.g.
ECC errors which happened during the last transfer.
