On the CCMP1 SOMs, we only consider a single system partition called UBI,
with many UBI volumes.
The variable 'singlemtdsys' allowed to change between this and
a system with multiple MTD partitions with one UBI volume each
(old approach on CC6UL).
This commit removes the variable and uses the logic as if it was set.

This code path was added in the context of single MTD layout support for
ccimx6ul boards, but it was being executed in the default storage layout use
case as well. This could trigger a race condition in which one code path
deletes the mount point while the other one is still setting it up, causing
partitions to not be mounted automatically (specifically, the "update"
partition).
Since both code paths are mutually exclusive in our implementation, reflect
this by making sure that the single MTD layout path is executed only when said
layout is enabled in the U-Boot environment.

(cherry picked from commit 9a7ea10a4dfb74651f865f125372604fe6840a10)
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.

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.
