[PATCH] arm: dts: stm32: Drop redundant status=okay

[Krzysztof Kozlowski]

Device nodes are enabled by default, so remove confusing or duplicated
enabling of few nodes.  No practical impact, verified with dtx_diff.

I assume the "no practical impact" means DTs are identical before/after 
this patch ? If yes,

No, DTS cannot be identical in this case because one had status, new one
does not have. Practical impact means... visible impact in practice. How
to say it more clearly?

To illustrate: this is "no practical impact":

Sorry, yes, this ^ is what I meant and obviously wrote too fast and too 
inaccurately. My RB still stands. Thanks
