(cherry picked from commit 9b99c0b073)
* Replace the hard-coded '/etc' with ${sysconfdir}
* Extend the mmcblk check to prevent updating the environment configuration
when booting from the EMMC (even though the kernel command line root
passed is in the form of /dev/mmcblk).
* Switch the conditional inherit to inherit_defer as it depends on
IMAGE_FEATURES to avoid parse-time ordering issues.

Both CC93 and CCMP2 store the environment at the end of BOOT1 partition
and the redundant environment at the end of BOOT2 partition. Reuse the
'fw_env.config' file defined for CC93 for both platforms, and also include
CC91 in the process.

This commits adds the CCMX91 platform to the DEY
build system. Furthermore, it creates generic ccimx9
support to be used for the CCiMX91 and CCiMX93
platform.

On devices with NAND as storage media, a post install script
modifies the fw_env.config file basing on the NAND geometry.
This only happens once after deployment, typically on production
environments. If the power is removed soon after the post install
script runs (which is a normal procedure on manufacturing
environments), there are chances that pending file system
operations have not been flushed, which may occasionally lead
to the fw_env.config file end up empty on the next reboot.
This commit adds a sync at the end of the post-install script
to guarantee the changes are written to the file system.

* Move Digi code out of the upstream files to minimize conflicts in
version migrations.
* Remove all the TEE client copied code and use the libteeclient library.
* Some fixes in the Optee-based environment encryption
* Some simplifications in CAAM-based environment encryption.

We can't run a post installation script in a readonly file system.
We need to provide a configuration file beforehand.

The HWID is populated on the device tree by the boot loader.
This can be used as a key modifier when encrypting the U-Boot
environment. Some old U-Boot versions however, did not populate
the HWID on the device tree. When updating firmware from an
old version to a new one, the library may not be able to read
the HWID from the DT and then be unable to unencrypt the
environment.
This patch implements a fall-back function to read the HWID
directly from the nvmem node (sysfs). Implementation has been
done for ccimx6 family only, where this case of old U-Boot
can happen.

(cherry picked from commit 222a91f213)
The config file /etc/fw_env.config is generated dynamically basing on
the partition table and, in the case of NAND-based SOMs, on the NAND
geometry. This is done on a postinst script that modifies the file on the
first boot of the target. Since this is not allowed on read-only-rootfs,
this commit adds a default fw_env.config file to use instead when
read-only-rootfs is enabled.

This is a replacement for u-boot-fw-utils. Adapt the u-boot-fw-utils patches
to this new library and include the same logic as the u-boot-fw-utils recipe
(generate and install the U-Boot environment configuration file in the rootfs)
For now, remove the u-boot-default-env dependency, since the package doesn't
exist in zeus.
