arm: mach-omap: Change mountpoint of boot partitions
If using EMMC and SD as bootsources, mounting the boot partition of both
devices to /boot makes trouble. Either the correct device is mounted to
/boot or a remount of /boot has to be performed.
To ensure this problem each MMCn bootsource will be mounted to his own
path in /mnt/mmcN.0
