ath12k driver adjusts ASPM state itself which leaves ASPM service
driver in PCI core unaware of the link state changes the driver
implemented.
Call pci_disable_link_state() and pci_enable_link_state() instead of
adjusting ASPMC field in LNKCTL directly in the driver and let PCI core
handle the ASPM state management.
