[PATCH] Revert "mci: imx-esdhc: Remove excess function"

[Sascha Hauer]

This reverts commit 8a6896971d093b9d8d1c36eb0d7af891b6ca5369.

With this patch it's no longer possible to call detect on the
physical device which is necessary for example to make environment
on MMC work. Unlike the commit message for 8a6896971d claims
mci_detect_card() is not called from mci_register().
