Subject: [PATCH v6 0/4] PCI: endpoint: add D-state change notifier support

In this series we added support to nofity the EPF driver whenever there
is change in the D-state if the EPF driver registered for it.

This series needed by the following series for epf driver to know whether
link is in D3Cold or D3hot to wake the host ('PCI: EPC: Add support to
wake up host from D3 states')
https://lore.kernel.org/linux-pci/1690952359-8625-4-git-send-email-quic_krichai@quicinc.com/T/

Changes from v5:
	- Fixed compilation errors & removed checks in the dstate_notify()
	  function as suggested by bjorn.
