crypto: mediatek - use AES library for GCM key derivation
The Mediatek accelerator driver calls into a dynamically allocated skcipher of the ctr(aes) variety to perform GCM key derivation, which involves AES encryption of a single block consisting of NUL bytes. There is no point in using the skcipher API for this, so use the AES library interface instead. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
