opp: Return genpd virtual devices from dev_pm_opp_attach_genpd()
The cpufreq drivers don't need to do runtime PM operations on the virtual devices returned by dev_pm_domain_attach_by_name() and so the virtual devices weren't shared with the callers of dev_pm_opp_attach_genpd() earlier. But the IO device drivers would want to do that. This patch updates the prototype of dev_pm_opp_attach_genpd() to accept another argument to return the pointer to the array of genpd virtual devices.
