I have found the STM ecosystem release notes and that solves this issue. The release notes can be found here: https://wiki.st.com/stm32mpu-ecosystem-v4/wiki/STM32_MPU_OpenSTLinux_release_note_-_v4.1.0#Minor_release_updates

Using the correct component version for linux kernel, stm-uboot, optee and tf-a resolves the issue. Particularly the specific u-boot version has to be used with the kernel version 5.15-stm32mp-r2.2 with resolve the problem specified.
