[CRYPTO] Allow AES C/ASM implementations to coexist
Herbert Xu [Sat, 5 Nov 2005 07:06:26 +0000 (18:06 +1100)]
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.
