Add SPL support to STM32MP13xx, so U-Boot SPL can initialize the hardware
without depending on any out-of-tree blobs. Enable the ability to start
OpTee-OS as a fitImage loadable, which allows booting the Linux kernel, DT
and OpTee-OS blob together from a single fitImage container file. This
avoids any ABI compatibility problems between OpTee-OS SCMI provider ABI
and the Linux kernel SCMI consumer ABI expectations, which led to unbootable
and irrecoverable systems after updates due to incompatible ABI changes.
