cpu/intel/haswell: Add s0ix support

Backport Broadwell's s0ix support to Haswell in preparation to unify
both platforms' CPU code. Note that only ULT variants support s0ix.

This option is currently unused, but will be put to use in subsequent
commits, when switching Broadwell mainboards to use Haswell's CPU code.

Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 remains identical.
