[PATCH 1/7] x86: remove AMD Élan remnants

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

There is one more leftover line in Kconfig and the detection for
AMD Generation 4 CPUs (5k86 and Élan) that can now get removed
following the increase of the minimum CPU level to 586TSC.
