PCI/pwrctrl: Do not try to power on/off devices that don't need pwrctrl
pci_pwrctrl_is_required() detects whether a device needs PCI pwrctrl
support. It is currently used in pci_pwrctrl_create_device(), but not in
pci_pwrctrl_power_{on/off}_device() APIs. This leads to pwrctrl core trying
to power on/off incompatible devices like USB hub downstream ports defined
in DT.
Add this check to prevent pwrctrl core from poking at wrong devices.
