rpi: kernel: detect stack corruption when calling the scheduler
This option checks for a stack overrun on calls to schedule(). If the
stack end location is found to be overwritten, always panic as the
content of the corrupted region can no longer be trusted. This is to
ensure no erroneous behaviour occurs which could result in data
corruption or a sporadic crash at a later stage once the region is
examined. The runtime overhead introduced is minimal.
