We'll need pm_genpd_add_subdomain() to be EXPORT_SYMBOL_GPL'ed so
clk-qcom can be built as a module.

It would also be nicer if this parent/child relationship can
somehow be represented in data (struct gdsc) that gets passed to
the gdsc driver which then sets it up, instead of individual
clock drivers doing it.
