I don't think the style is to have a single container node anymore.
Instead, each pin gets a different node and then pinctrl-0 has a list of
phandles to the different nodes. qcom maintainers may have more input
here.

Also, this should really go into a different section than here. I
thought the style was to have a 'board specific' pinctrl section.
