it83xx: watchdog: print LP on watchdog warning
It's difficult to debug problems with single watchdog warning.
This patch will print IPC and LP registers continually if watchdog
warning is fired.
BRANCH=None
BUG=b:79733639
TEST=waitms 1000, EC print warning message but no reset.
waitms 3000, EC print warning message and then reset.
On bip, EC is powered by servo only. And we got the following
watchdog warning message:
And we refer to assembly code, the IPC indicates CPU is executing
instructions in "gpio_get_level()"
(IPC:00002408, IPC:00002404, IPC:000023fc, IPC:0000240e),
and calling from "chipset_pre_init_callback()" (LP:0000101e).
