To support system suspend/resume or runtime suspend/resume, need to use the function pci_set_power_state() to change the power state which requires at least method _PS0 or _PR0 be filled by platform for v3 hw. So check whether the method is supported, if not, print a warning. A Kconfig dependency is added as there is no stub for acpi_device_power_manageable().
