This commit adds u-boot swupdate support for all platforms.
Now u-boot can be updated with all our supported update
options. Currently it will only update first partition
u-boot partition.

ConnectCore 6 based products require the use of the 'upgrade_available' environment flag to save the
bootcount value between resets. Extend the use of this U-Boot variable for single system updates and
updates based on files.

This commit adds sha256 entry for the script files into
the sw-descrition. It is necessary for the Trustfence
authentication to have the included script files signed.

We expect new types of SWU update packages to be created in the future. To avoid splitting
all the code in different classes based on the update type, create the generic class
'dey-swupdate' to hold all the custom code and the 'dey-swupdate-common' class to hold all
the required variables. This basically renames the old 'swupdate-files' and 'swupdate-files-common'
classes.
While on it, reorganize the 'swupdate-images' recipe to move variable declarations and
functionallity to the correct place:
- Move all variable declarations to 'swupdate-digi-common' class and organize them in
functional groups.
- Improve the way files are included in the 'SWUPDATE_IMAGES' by using the update type
variables.
- Move the update script copy to the 'do_swuimage' prepend function. Until now, the copy
process was executed in the 'fill_description' method, which should only touch the
'sw-description' file.
- Rename some variables to use 'SWUPDATE' prefix.
- Minor cosmetic changes.

Implement a new mechanism to allow users to create update packages based on files and folders to modify
the active system.
This is done through the new class 'swupdate-files', which creates a tar.gz update file in the image
distribution output directory containing all the files and directories to create/update. The 'tar.gz'
file is used later by the 'swu-images' recipe to generate the final SWUpdate package. The SWU package
installation process extracts the tar.gz file in the root folder ("/") of the active system.
Users can specify the list of files and directories to include in the update package using the
'SWUPDATE_FILES_LIST' variable. These files will be directly copied from the generated system rootfs and
placed in the tar.gz archive. Additionally, users can provide their custom 'tar.gz' file to use in the update
by specifying its location in the 'SWUPDATE_FILES_TARGZ_FILE' variable. In any case, all the paths to include
in the update package must be relative to "/", as it is the base directory where tar.gz file contents are
extracted.
The update process for dual boot systems sets a new u-boot flag so that active bank is not swapped once
installation is complete and system reboots.
The SWU update mechanism based on files provides a custom update script which takes care of preparing the
system for the installation process. Just like in the SWU updates based on images, users can customize this
script or override it with the 'SWUPDATE_SCRIPT' variable, specifying the location of the new script to use.
If both the 'SWUPDATE_FILES_LIST' and 'SWUPDATE_FILES_TARGZ_FILE' variables are empty, a standard images
SWUpdate package will be generated instead.
