[PATCH 10/10] stm32mp1: spl: Copy optee nodes to target FDT for OP-TEE payloads

[Alexandru Gagniuc]

OP-TEE does not take a devicetree for its own use. However, it does
pass the devicetree to the normal world OS. In most cases that will
be some other devicetree-bearing platform, such as linux.

As in other cases where there's an OPTEE payload (e.g. BOOTM_OPTEE),
it is required to copy the optee nodes to he target's FDT. Do this as
part of spl_board_prepare_for_optee().
