arch/arm: add an armv8.3a core
The armv8.3a generation is a cumulative extension to armv8.2a. Since gcc correctly enables the appropriate extensions based on the core name, we don't really need to introduce a separate config for armv8.3a, and we can piggyback on armv8a. This new core is AArch64 only. Signed-off-by: "Yann E.
