lm4f: fix watchdog trace
After commit 84a286b1, the watchdog handler was no longer properly
connected to the interrupt vector.
Also add a couple of flushes to get all the traces.
Signed-off-by: Vincent Palatin <vpalatin@chromium.org>
BUG=chrome-os-partner:8721
TEST=type "waitms 5000" in the EC console to trigger the watchdog and
check we get the right serial trace.
