drivers: sh: Disable PM runtime for multi-platform r8a7740 with genpd
If the default PM domain using PM_CLK is used for PM runtime, the real PM domain(s) cannot be registered from DT later. Hence do not enable it when running a multi-platform kernel with genpd support on an r8a7740. The R-Mobile PM domain driver will take care of PM runtime management of the module clocks. The default PM domain is still needed for: - platforms without genpd support, - the legacy (non-DT) case, where genpd may take over later, except for the C5 "always on" PM domain.
