cpu/amd: Detect any conflicts between sysinfo and the stack region
When increasing the number of supported CPUs on AMD Family 10h/15h
systems there is a relatively high chance of causing a collision
between the CAR global variable region and the AP stack space.
Such collision was noted when increasing the number of supported
CPUs to 32 on the ASUS KGPE-D16.
Detect collision at runtime and print a warning if collision is
present.
