This commit fixes the default secure storage path
to /mnt/data/tee instead of /var/lib/tee. This will
store all secure storage keys in that path and will
keep them even during rootfs updates.

The default secure storage (/var/lib/tee) is a tmpfs and not persistent
across reboots. Change it to the data partition (/mnt/data/tee) when
TrustFence file system encryption enabled
For the log file, do use the /var/log/ directory instead of default
/data

Starting with OP-TEE v4.0.0, the use of a test key is no longer supported.
The Hardware Unique Key (HUK) is now always derived from the programmed OTP bits.
As a result, the Digi custom `CFG_OTP_HUK` flag is obsolete and has been removed.

This commit integrates optee-client support from the meta-st-openstlinux layer,
based on the openstlinux-6.6-yocto-scarthgap-mpu-v25.03.19 tag.

This commit imports the sign-stm32mp bbclass from the meta-st-stm32mp layer to
allow customization. The main customization ensures that the search_path()
function does not raise a build exception if the signing tool or keys are not
present in the PATH before starting the build process.
In our case, we do not need to manually install the tools or generate the keys
beforehand, as this is automatically handled by Yocto in our DEY distribution.

This commit removes the scp-firmware recipe, as it has been integrated into the
optee-os recipe with the latest v4.0.0 from the ST BSP release. This update is
based on the openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 tag for Yocto 5.0
(Scarthgap).

The SCP firmware introduces too much verbosity (with
timestamp included) in the middle of the boot log
between the TF-A and U-Boot.
Reduce the log and remove compiler flags for errors
on unused variables (banner strings).
This removes the following messages from SCP firmware:
[ 0.000000] SCP-firmware v2.12.0-dev
[ 0.000000]
[ 0.000000] [FWK] Module initialization complete!

ST_OPTEE_DEBUG_TRACE is set to 0 if ST_DEBUG_TRACE is set to 0.
However, on the optee source code, if ST_OPTEE_DEBUG_TRACE=0 the
log level is automatically set to 3 (INFO) resulting in a very
verbose optee log.

By default, the secure storage path in the REE is "/var/lib/tee". It is
part of the rootfs, and thus, it gets lost on a firmware update.
This commit changes that path to a different partition "/mnt/data/tee"
when Trustfence file-based encryption is enabled.

Commit 92969f0c4 ("plat-stm32mp1: Remove CFG_STM32_BSEC_WRITE dependency with
debug configuration OP-TEE") on OP-TEE source code, removed the link between
the BSEC WRITE feature with DEBUG feature, so now by default it is enabled.
This reverts commit 2395378ec4.
