Why can't we extend support in power domains code to have
multiple domains for a single device node? i.e. power-domains =
<&pd_isp>, <&pd_foo>, <&pd_bar>, and then pick the right one with
power-domain-names or something like that? Making a subnode
(which seems to turn into a child platform device?) seems like a
quick solution for larger problems.
