sc8180x PCIe clocks and resets are different from the common pcie
binding, this warrants the oneOf clause for the clocks and resets

There is no "common" part for sc8180x in this binding. sc8180x is
customized.

> binding, this warrants the oneOf clause for the clocks and resets

Your subject and commit suggests you are now adding new customization
for SC8180x, but it is already there! Clocks, interrupts, regs etc.
Therefore the commit msg does not fit the contents of the patch. Instead
say that you fix something or change, because of foo and bar.

Otherwise it looks like some old patch rebased onto new kernel so it
does not match at all.

It's not oneOf.

Why do you even need this here? It's already there.

And this looks wrong. Drop.
