MLK-9819: ARM: mx6sx: clear WDOG3 Power Down Enable bit for i.mx6sx
Since we use WDOG_B reset now, we have to clear WDOG3 Power Down Enable
bit to avoid system reboot during normal kernel boot.
For mx6sxsabresd board, we have to make sure pad setting for WDOG_B ready
before mux ready, otherwise also cause reboot. But that dependes on hardware
design, only need on mx6sxsabresd board.
