kernel: rootfs auto-mount on ubi

Similar to the rootfs hacks on NOR flash devices, this series
introduces support for auto-attaching (ubi device), auto-creating
(ubiblock device) and mounting the "rootfs" (ubifs or squashfs)
volume.
This is needed so OpenWrt can start without relying on the bootloader
to pass the ubi.mtd, ubi.block, rootfs and rootfstype parameters, but
instead auto-detect the root filesystem according to a simple convention.

scripts: add ubinize-image.sh to generate ubi images

This is a wrapper for the ubinize tool which integrates auto-generation
of the ubinize.cfg for common volume layouts with and without a kernel
volume.
It supports auto-detecting the rootfs-type and decides whether or not
to include a rootfs_data volume based on whether the rootfs is ubifs
or not (and thus is read-only and needs rootfs_data ubifs overlay).
The script allows to create layouts as found in all current
ubinize{,-overlay}.cfg files using

ubinize-image.sh --no-kernel root.{ubifs,squashfs} output.ubi $UBI_OPTS

It also includes support for adding ubootenv and ubootenv2 volumes
typically used by U-Boot for storing its environment in UBI using the
"--uboot-env" parameter.
