PM / Domains: Silence compiler warning for an unused function

Browse Source 
The only remaining caller of genpd_poweron() is conditionally compiled
based on CONFIG_PM_GENERIC_DOMAINS_OF, so we get a warning when that is
unset.

By moving the locking/unlocking of the genpd outside genpd_poweron(), thus
to the caller, genpd_poweron() becomes redundant.

Within this context let's then rename the wrapper function,
__genpd_poweron(), to genpd_poweron() as it will then be consistent with
its friend genpd_poweroff().

This change silence the warning about the unused function.
