base-files: allow non-standard rootfs volume name in UBI in sysupgrade
This commit allows to use non-standard UBI volume name as the rootfs
volume in sysupgrade.
ex.:
The U-Boot on Buffalo WXR-2533DHP checks existence and checksum of
"ubi_rootfs" volume when booting, so this name is required.
OpenWrt currently provides several patches:
490-ubi-auto-attach-mtd-device-named-ubi-or-data-on-boot.patch
491-ubi-auto-create-ubiblock-device-for-rootfs.patch
492-try-auto-mounting-ubi0-rootfs-in-init-do_mounts.c.patch
to facilitate ubi rootfs automount. However the upstream kernel
also supports the means of booting from a fully custom ubi
partition name and ubi volume name via bootargs/kernel's cmdline
parameters:
ubi.mtd=mtd_partition_name
ubi.block=rootfs_volume_name
root=/dev/ubiblock$X_$Y
