There is an I2C EEPROM on the SoM module. Enable the driver for it.

Using the generic "lvds-panel" driver will allow a user to specify the
display timing within the device tree. This was tested with both single
and dual link LVDS panels.

This is required to compile overlays that can be loaded by U-Boot.

With the layers in a single repo, we don't need layer-specific CI configs,
READMEs or license information anymore.

Use the new SPDX names as done in later Yocto releases like Kirkstone.
A separate patch applied for Dunfell that backports the new license
names makes sure that we stay compatible with both releases.

We override the default value of UBOOT_ENTRYPOINT set in meta-freescale
to get rid of the alignment kernel boot warning. For this to work in both,
Dunfell and Kirkstone, we need to apply some fixes.

This adds the necessary changes fpr compatibility with the v2.6-based
TF-A code from meta-freescale's imx-atf.

At the same time we add a compat bbappend for dunfell to stay with
the previously used TF-A version.

* Remove deprecated patches
* Use default branch and ref from base repo
* Specify UART for i.MX8MM SoM in machine config
* Specify ATF_PLATFORM for i.MX8MM SoM in machine config

Copied from the imx8mm-evk configuration in meta-freescale.

Weaken the include for the path in Dunfell releases and add another
reference to the path in Kirkstone so we can be compatible with both
releases.

In commit

ce868964 ("meta-ktn-imx: u-boot-ktn-common.inc: Remove unneeded do_compile() override")

we removed the do_compile() override, but this is still needed, at
least in Dunfell. Revert this.

This is useful for backwards compatibility with older releases such as
Dunfell which might need additional changes/backports.

This fixes the following type of warning:
