Satyanarayana K V P e9dea328e8 drm/xe: Introduce fault injection for guc mmio send/recv. 
Fault can be injected with below steps.

FAILTYPE=fail_function
FAILFUNC=xe_guc_mmio_send_recv

echo > /sys/kernel/debug/$FAILTYPE/inject
echo $FAILFUNC > /sys/kernel/debug/$FAILTYPE/inject
printf %#x -5 > /sys/kernel/debug/$FAILTYPE/$FAILFUNC/retval

echo N > /sys/kernel/debug/$FAILTYPE/task-filter
echo 10 > /sys/kernel/debug/$FAILTYPE/probability
echo 0 > /sys/kernel/debug/$FAILTYPE/interval
echo -1 > /sys/kernel/debug/$FAILTYPE/times
echo 0 > /sys/kernel/debug/$FAILTYPE/space
echo 1 > /sys/kernel/debug/$FAILTYPE/verbose
