Subject: [PATCH 05/10] x86: add X86_64 dependency to x86_64 specific symbols in Kconig.x86_64

To ease unification of Kconfig.i386 and Kconfig.x86_64
add X86_64 dependencies to all x86_64 specific symbols.

This patch introduce no functional changes but is one step
towards unification. This smaller step is used to ease
review of the patch set.
