Subject: [PATCH] crypto: caam/qi2 - fix Chacha20 + Poly1305 self test failure
key buffer is not copied in chachapoly_setkey function,
results in wrong output for encryption/decryption operation.
fix this by memcpy the key in caam_ctx key arrary
Fixes: c10a53367901 ("crypto: caam/qi2 - add support for Chacha20 + Poly1305")
