x86/topology: Remove redundant ENABLE_TOPO_DEFINES

Commit c8e56d20 ("x86: Kill CONFIG_X86_HT") removed CONFIG_X86_HT
and defined ENABLE_TOPO_DEFINES always if CONFIG_SMP, which makes
ENABLE_TOPO_DEFINES redundant.

This patch removes the redundant ENABLE_TOPO_DEFINES and instead uses
CONFIG_SMP directly
