In a loading chain SPL -> ATF (->OP-TEE) -> U-Boot, ATF and a subsequent OP-TEE will re-use the same fdt as the U-Boot target and may need the information about usable memory ranges.
Especially OP-TEE needs this to initialize dynamic shared memory (the only type U-Boot implements when talking to OP-TEE).
So allow spl_fixup_fdt() to take a fdt_blob argument, falling back to the existing CONFIG_SYS_SPL_ARGS_ADDR if needed and call it from the ATF path as well.
