[CRYPTO] Allow AES C/ASM implementations to coexist

As the Crypto API now allows multiple implementations to be registered for the same algorithm, we no longer have to play tricks with Kconfig to select the right AES implementation. This patch sets the driver name and priority for all the AES implementations and removes the Kconfig conditions on the C implementation for AES. Signed-off-by: Herbert Xu <[email protected]>
