Platform firmware may not be able to access config space to program
ASPM. For instance, devices behind Intel VMD are not configured by the
BIOS.
So add a helper to let drivers have an option to enable ASPM.

BIOS may not be able to program ASPM for links behind VMD, prevent Intel
SoC from entering deeper power saving state.
So enable ASPM for links behind VMD to increase battery life.

This can be fixed by not runtime suspend the controller at all.
So disable runtime suspend for EJ168 xHCI device.

PCI_DEV_FLAGS_NO_D3 should not be used outside of PCI core.
Instead, we can use pci_save_state() to hint PCI core that the device
should stay at D0 during suspend.
