watchdog: imx_sc_wdt: Don't disable WDT in suspend
Parts of the suspend and resume chain is left unprotected if we disable
the WDT here.
>From experiments we can see that the SCU disables and re-enables the WDT
when we enter and leave suspend to ram. By not touching the WDT here we
are protected by the WDT all the way to the SCU.
