DT maintainers dislike this fake bus container node. Please get rid of
it by putting fixed regulator node directly under root, in the following
naming schema:

Why is it being disabled?

I do not find the bindings for this property, neither how driver
supports it.

If these compatibles are not documented or used, we can drop them? I
guess we only need "syscon" to get it work?

It might make more sense to put it directly under root like what
fsl-ls1043a.dtsi does.

I understand "fsl,imx21-wdt" is the one that kernel driver matches, but
why do we need "fsl,ls1043a-wdt" here?
