Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is needed since commit [1] that changed U-Boot/stm32mp15 to detect OP-TEE availability by probing the resource instead of relying on U-Boot configuration. The software sequence implemented by [1] is fine but U-Boot DTS/DTSI files were not updated accordingly since, hence OP-TEE presence is never detected by U-Boot, preventing Linux kernel from using OP-TEE resources.
For consistency and to synchronize stm32mp15 DTSI files (excluding U-Boot specific DTSI files) with the Linux kernel ones, this change also moves the OP-TEE reserved memory nodes from board generic DTSI files to U-Boot specific board DTSI files.
