In a step to move away from using genpd's name based APIs, such as the
pm_genpd_add_subdomain_names(), provide an API to lookup an already
initialized generic PM domain by its firmware node.

This API would typically be a called from SOC specific code, to fetch a
handle to the domain. Especially convenient to configure subdomains and
when the hierarchy of the domains are described in DT.

Do note, before pm_genpd_init() is invoked to initialize a generic PM
domain, it's the callers responsibility to assign the new ->fwnode
pointer in the struct generic_pm_domain, to enable pm_genpd_lookup() to
find the domain.

I have no problems with that, but do you have a user for it?

Amit Daniel Kachhap, posted a patchset which is adding subdomains
configured from DT for Exynos. It's from there the idea to this patch
comes from. Amit is about to post a new version, based on this patch.
