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.
