[U-Boot] [PATCH v3 24/26] ARM: SPL/FIT: differentiate between arm and arm64 arch properties

[Andre Przywara <andre.przywara@arm.com>]

Since the SPL FIT loader can now differentiate between different
architectures, teach it how to tell arm and arm64 apart when a FIT
image is used.
We just support those two for now, as these are so far the only sensible
alternatives.
