Finally, after two years, put in real code for stop_ap(). Code has to be

moved to stage1 ROM code. Make the struct for nodeid/coreid generic to 
x86. Create the functions for existing architectures are a model for 
future architectures (VIA coming soon we hope). 

Move includes so that things build correctly now. 

This is actually a small patch that impacted a number of files due to 
include order changes. This is build and boot tested on simnow and 
build tested on geode.
