minute-ia: ish software panic
Adding functions for software panic to ISH. This includes
panic_set_reason, panic_get_reason and software_panic.
Added extra output when a software panic is detected.
Had to touch nds32/panic.c in order to make panic_sw_reasons
common.
BUG=b:134502392
BRANCH=none
TEST=Verified with crash assert, with CONFIG_DEBUG_ASSERT defined
