Philip Chen 0037fb8dfc system: Log PC and task id on watchdog ...

For debug, in common code let's log the watchdog PC
and task id as our SW panic params.

BUG=chromium:790006
BRANCH=none
TEST=manually test scarlet rev2 from a1-a3, b1-b2:

(a1) Add 'while(1);' in button ISR
(a2) Boot and press the button
(a3) When watchdog is triggeried, check with 'panicinfo'
that saved R5 is the PC for button ISR.

(b1) 'crash watchdog' in EC console
(b2) Check with 'panicinfo' that CONSOLE task id is saved in
EXCEPTION and PC is saved in R5.
