Forward ports for changes from legacy meta-ktn and meta-ktn-imx repo

This MR contains patches from the legacy meta-ktn repository that have been added there after the import of the layer into the new BSP repo. The following flow was used for porting:

Create patches in meta-ktn:

git format-patch 3fb800d..08831fc

Create patches in meta-ktn-imx:

git format-patch 448b6d5^..e15f336

Apply patches in new BSP:

git am -3 --directory=layers/meta-ktn ~/work/yocto-ktn/layers/meta-ktn/*.patch
git am -3 --directory=layers/meta-ktn-imx ~/work/yocto-ktn/layers/meta-ktn-imx/*.patch
