spl: fit: Add ability to jump to Linux via OPTEE-OS on ARMv7a
Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a to SPL. This is already supported on ARMv8a, this patch adds the ARMv7a support. Extend the SPL fitImage loader to record OPTEE-OS load address and in case the load address is non-zero, use the same bootm-optee.S code used by the U-Boot fitImage jump code to start OPTEE-OS first and jump to Linux next.
