-names should go last

Per the cover letter:

- Moved pinctrl-names before pinctrl-N (Konrad);

You explicitly requested this in https://lore.kernel.org/linux-arm-msm/[email protected]/#t
but we also backtracked on it somewhat for consistency with other -names, and the general state of this file.

Maybe we should apply v1 of this specific patch?

Konrad is technically correct as per [1] but, for consistency, since all of the
other nodes in msm8976.dtsi are following that order for pinctrl, this version of
the patch is correct.

That, unless anyone wants to reorder everything in this file as per [1], which
may or may not be worth the noise.

Agreed, but we made up our minds since 2022-12-15 ;)
