omap4-common: fix permission for sdcard0 and mark sdcards nonemulated

This change fixes applications on sd-card vanishing on reboot due to
sdcard0 being mounted as root (as /ss is mounted as root) and
both sdcards not being marked as nonemulated.

Loglevel 8 -> 3

Do we still need this verbosity level for the init ?
