Fixes and Sandybridge support for lapic cpu init
- preprocessor macros should not use defined(CONFIG_*) but
just CONFIG_*
- drop AMD CPU model 14XXX config variable use. Those do not exist.
- skip some delays on Sandybridge systems
- Count how long we're waiting for each AP to stop
- Skip speedstep specific CPU entries
