CRISv32: add unreachable() to BUG()
Add an unreachable() in the BUG() implementations, to get rid of several warnings similar to the one below: kernel/sched/core.c: In function 'pick_next_task': kernel/sched/core.c:2690:1: warning: control reaches end of non-void function [-Wreturn-type] Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Jesper Nilsson <jespern@axis.com>
