UPSTREAM: soc/amd/stoneyridge: Create a HALT_THIS_AP callout
It was required for all cores use the same CAR teardown function
(exit_car.S and gcccar.inc). AGESA has already been modified to do the
AP to do the call out. Create assembly code to call chipset_teardown_car
and then enter an endless loop with halt instruction. Then create the
call out that will call this new assembly code.
BUG=b:70338633
AGESA COMMIT=3313d277
TEST=Created a debug version of AGESA that would print the returned
status of HALT_THIS_AP. Build code without the fix, see the return.
Build code with the fix, see that there's no return.
