nb/intel/x4x: Use parallel MP init
Use parallel MP init code to initialize all AP's.
Also remove guards around CPU code where all platforms now use
parallel MP init.
This also removes the code required on lapic init path for
model_6fx, model_1017x and model_f4x as all platforms now use the
parallel MP code.
Tested on Intel DG41WV, shaves off about 90ms on a quad core.
