[PATCH] mmc_rescan: reduce verbosity

["Eric Bénard" <eric@eukrea.com>]

since commit 820f2bcfdc32cd90061224c930cf670f961e12d1 mmc_rescan
includes a pr_info which prints 4 lines each second for hosts configured
with MMC_CAP_NEEDS_POLL. Tested on i.MX51's sdhci-esdhc.
This patch increase log level to debug (but maybe the right solution
would be to remove this log).
