Watchdog timeleft returns unexpected huge value for first read, followed by correct expected values. Unexpected huge value reappears after few minutes. Issue is resolved by updating the existing hardware workaround to read WCV_HI along with WCV_LO. Signed-off-by: Pradeep Turaga Shakthi <pturagashakt@marvell.com>
