crypto: x86/aes - drop scalar assembler implementations

Browse source

The AES assembler code for x86 isn't actually faster than code
generated by the compiler from aes_generic.c, and considering
the disproportionate maintenance burden of assembler code on
x86, it is better just to drop it entirely. Modern x86 systems
will use AES-NI anyway, and given that the modules being removed
have a dependency on aes_generic already, we can remove them
without running the risk of regressions.
