Revert "x86: don't compile vsmp_64 for 32bit"
Partial revert of commit 129d8bc828e011bda0b7110a097bf3a0167f966e titled 'x86: don't compile vsmp_64 for 32bit' Commit reverted to compile vsmp_64.c if CONFIG_X86_64 is defined, since is_vsmp_box() needs to indicate that TSCs are not synchronized, and hence, not a valid time source, even when CONFIG_X86_VSMP is not defined.
