Device tree overlays now have the extension 'dtso' that
distinguishes them from board 'dts' files, so there is
no need for a prefix '_ov_' to tell if a file contains
a DT overlay.
To make them shorter and easier to tell the platform they
are for, change the filename format to:
<platform-name>_<functionality>.dtso
where <platform-name> can be the name of the SOM or the
name of the DVK, so there is no need either to specify
'som' or 'board' on the filename.

Improve boot attempts message showing not only the current boot attempt
but also the limit:
(boot attempt 1/3)
Print the message only when the bootcount mechanism is active, i.e. when
the bootlimit is defined (not zero), and when bootcount is > 0.

Until now, for dualboot systems, all boot variables were calculated on each boot depending on the value of the
'active_system'. These variables are used to boot the device but were not saved, which could lead to a missmatch
between their value in the environment and their required values to correctly boot the system. This commit
simplifies a bit the variables calculation and adds a block to synchronize their value in the environment.

The 'bootcount' value is now incremented and stored in the system on every boot and
not only then the 'upgrade_available' flag is set. Also, ensure the value is cleared
when the 'altboot' script is executed by running the new U-Boot command 'bootcount reset'.

Number of bootup logos is now configured using fbcon=logo-count parameter,
so use it instead of our deprecated custom code in the kernel.
For backwards compatibility, we add this parameter in the u-boot boot
script for all platforms but the ccimx93, where this is directly handled
by u-boot (v2022.04).

U-Boot has embedded support to handle bootcount tries.
When the limit of tries is reached, U-Boot runs the script
in `altbootcmd` rather than the usual `bootcmd`.
This other script resides on meta-digi-dualboot layer.

When DualBoot mechanism is enabled and an update is pending,
the boot script needs to change certain variables and save the
environment.
The regular boot script already changes a number of variables,
such as 'extra_bootargs' and 'overlays' by appending strings to
the already existing values. Saving the envionment may make these
grow endlessly with each iteration of the boot script.
For this reason, move the DualBoot check as the first thing in
the script, save the environment if needed, and then continue
with the normal flow, that changes variables before booting
but doesn't save them.
On certain scripts, this allows us to get rid of some instructions
for resetting the overlays variable.

The support for dualboot was integrated on meta-digi-dualboot layer, but it
really depends only on environment variable 'dualboot' so we'd better
integrate the support on the scripts in meta-digi, to avoid synchonization
problems between both layers.
This also allows to be able to easily enable dualboot in U-Boot with the
variable, without needing to update the script on the linux partition.

On these boot scripts, this variable is not used, so we can remove it.
Besides, it's generated by U-Boot code.

This overlay added cooling devices for all quad cores.
On the latest BSP, the SoC device tree include contains all four
cooling devices and the newest U-Boot is able to delete the nodes
for non-existing cores, so there's no need for this overlay
anymore.
