[PATCH v4 3/3] watchdog: pretimeout: update PSC reason in panic pretimeout governor

Update the PSC reset reason by invoking
set_psc_reason(PSCR_WATCHDOG_PRETIMEOUT) from the panic governor's
pretimeout handler before calling panic(), so the reset cause is
committed to persistent storage before the system goes down.
