cpu/amd/fam10h-fam15h: Add new wait_ap_stopped function
Under certain conditions, such as when microcode updates are
being performed, it is important to make sure all APs have
finished updates and are halted before continuing with the
boot process.
Add a new wait_ap_stopped() function to allow for this
functionality to be added to the appropriate mainboard
romstage source files.
