Rewrite and clean up mmc_rescan() to properly retry frequencies lower than 400kHz. Failures can happen both in sd_send_* calls and mmc_attach_*. Break out "mmc_rescan_try_freq" from the frequency selection loop. Symmetrize claim/release logic in mmc_attach_* API, and move the sd_send_* calls there to make mmc_rescan easier to read.
