STM's st-machine-common-stm32mp.inc file automatically incorporates "optee" to
MACHINE_FEATURES as long as BOOTSCHEME_LABELS contains "optee". Since we
recently modified the ccmp15's labels to only contain "opteemin", this is no
longer the case, which leads to:
* optee packages (optee-client, optee-os) not getting installed in images and
SDKs
* optee patches for environment encryption not being applied to libubootenv
Add the feature manually to fix these two issues
