[U-Boot] [PATCH 1/3] sysboot: Add support for ubifs to the sysboot command

[Hans de Goede]

ubifs does not go though the generic block layer because mtd devices
are special, so the "any" filesystem option to sysboot does not work,
this adds support for a "ubifs" filesystem to the sysboot command which
makes it possible to boot from ubifs using an extlinux.conf file.
