Subject: [PATCH v7 0/4] PCI: endpoint: add D-state change notifier support

In this series we added the 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 because EPF driver
needs to send PME when the link is D3hot and toggle wake when the link
is in D3Cold('PCI: EPC: Add support to wake up host from D3 states').

The following link is for older series a newer series will be sent after
rebasing on this series.
