If the missing clock is the problem then you also have to tell the clock
core that the dummy clock shall be provided to the watchdog, something
like:

	clkdev_add_physbase(clks[IMX5_CLK_DUMMY], MX53_WDOG1_BASE_ADDR, NULL);
	clkdev_add_physbase(clks[IMX5_CLK_DUMMY], MX53_WDOG2_BASE_ADDR, NULL);

similar is missing for i.MX51 as well
