This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1.
Main changes:
* Re-structure the ioctl switch call for all drivers as follows:
	switch (cmd) {
	case WDIOC_GETSUPPORT:
	case WDIOC_GETSTATUS:
	case WDIOC_GETBOOTSTATUS:
	case WDIOC_GETTEMP:
	case WDIOC_SETOPTIONS:
	case WDIOC_KEEPALIVE:
	case WDIOC_SETTIMEOUT:
	case WDIOC_GETTIMEOUT:
	case WDIOC_GETTIMELEFT:
	default:
	}

This to make the migration from the drivers to the uniform watchdog
device driver easier in the future.
