Hector Palacios 91bfa01a52 udev: automount UBI volumes named "linux" or "recovery"
Traditionally, platforms based on NAND, used one UBI volume
per MTD partition.
Now it's possible to use only one MTD partition containing many
UBI volumes.

Hector Palacios 435e085690 udev-extraconf: update mount scripts to support systemd
The current scripts used the standard mount binary at /bin/mount
for mounting the partitions. Systemd however seems to have a monitor
that eventually umounts such partitions if not mounted by systemd's
specific command 'systemd-mount`.

For platforms using systemd, we need to use this binary together with
parameter --no-block so that partitions are mounted correctly during
the boot process.

This commit merges the two scripts for Digi-handled partitions into
just one:

	mount_bootparts.sh
                          \
                           +--> mount_digiparts.sh
                          /
        mount_partition.sh

The merged script:
 - checks if running with systemd, to use its binary.
 - checks if running with busybox, to not use the unsupported '-o'
   attribute.
 - checks if mounting the 'linux' partition, to mount it read-only.
 - checks for already-attached UBI devices, to avoid re-attaching.

This commit also combines the Digi-handled partitions (linux, update)
into the same udev rule, to simplify it, and breaks the rules lines
for readability.
