Takes care of retrieving a FsStorage object for any FAT eMMC BIS partition, mounting it via FatFs and creating a virtual devoptab device that can be used to carry out FS operations. All write operations have been stubbed, disabled or ifdef'd out of the code. Other changes include: * cert: update code to use the new BIS storage interface. * defines: remove BIS_SYSTEM_PARTITION_MOUNT_NAME macro. * devoptab: slightly improve macros. * devoptab: add operation table for FatFs devices. * devoptab: add rodev_fstat(). * devoptab: add devoptabMountFatFsDevice(). * fatfs: update diskio code to use the new BIS storage interface. * fatfs: update configuration. * save: update code to use regular C I/O calls instead of FatFs calls. * tik: update code to use the new BIS storage interface. * utils: remove eMMC BIS System partition (un)mount code.
