There is no need to pass a genpd struct to pm_genpd_remove_device(), as we already have the information about the PM domain (genpd) through the device structure. Additionally, we don't allow to remove a PM domain from a device, other than the one it may have assigned to it, so really it does not make sense to have a separate in-param for it. For these reason, drop it and update the current only call to pm_genpd_remove_device() from amdgpu_acp.
