[PATCH v4 00/11] Fixes, cleanups and updates for OP-TEE and TAs

[Uladzimir Bely <ubely@ilbers.de>]

This summarizes and partially updates previously sent patches to fix and
improve the recently merged OP-TEE changes. Labeling starts with v3 as
some patches were already sent out in v2.

Improvements over the individual patches:
 - update for WolfSSL in fTPM recipe
 - better unbinding of fTPM on tee-supplicant shutdown

Patch 11 might still have no effect and needs confirmation via larger CI
builds.

Changes since v3:
- Rework patch 4 in order to prevent conflicting parallel build of
linux-mainline for stm32mp15x and non-stm32mp15x machines for the
same distro and architecture.
- Replaced patch 11 with new one that guarantees `tpm` and `wolf`
symlinks creating before compilation source files. By default TA devkit
runs them in parallel and it sometimes results in race condition and
build error.
