armv8: fsl-lsch3: Copy Bootscript and header from NOR to DDR
To unify steps for secure boot for xip (eg. NOR) and non-xip memories
(eg. NAND, SD), bootscipts and its header are copied to main memory.
Validation and execution are performed from there.
For other ARM Platforms (ls1043 and ls1020), to avoid disruption of
existing users, this copy step is not used for NOR boot.
