PM / Domains: Allow overriding the ->xlate() callback
Allow generic power domain providers to override the ->xlate() callback
in case the default genpd_xlate_onecell() translation callback is not
good enough.
One potential use-case for this is to allow generic power domains to be
specified by an ID rather than an index.
