Ok, I guess this means the imx8mp clock driver in SPL is broken and we
can't easily fix the DM_WATCHDOG issue without it.  I don't really know
much about imx8 nor do I have any hardware which I could use to debug with
so I can't help much with this.

Maybe Peng, who wrote the clock driver, can comment?

Otherwise, the series which contains this patch also fixed the non-DM
reset in SPL so we could revert back to that if all else fails ...
