Allow compilation on Raspi (for ARMv8) Current master fails to compile for ARMv8 on Raspi cause gcc (version 10.2.1) does not like to cast between signed and unsigned vector types. This patch fixes it by using unsigned vector pointer for ARM to avoid implicite cast. closes https://github.com/official-stockfish/Stockfish/pull/4752 No functional change
