ext4: Use ext4 file system driver for ext2/ext3 file system mounts
Add a new config option, CONFIG_EXT4_USE_FOR_EXT23 which if enabled,
will cause ext4 to be used for either ext2 or ext3 file system mounts
when ext2 or ext3 is not enabled in the configuration.
This allows minimalist kernel fanatics to drop to file system drivers
from their compiled kernel with out losing functionality.
