Subject: [PATCH V7 0/4] Add PCIe support for IPQ9574

This series adds support for enabling the PCIe host devices (PCIe0, PCIe1,
PCIe2, PCIe3) found on IPQ9574 platform. The PCIe0 & PCIe1 are 1-lane Gen3
host and PCIe2 & PCIe3 are 2-lane Gen3 host.

[V7]    - Fixed review comments from Konrad, Krysztof, Manivannan and picked up review tags
          Rebased patch 4 on top of [1] for avoiding DBI/ATU mirroring
          Both dt_binding_check and dtbs_check passed and tested on ipq9574-rdp433

        - Dropped patches [1] and [2] for clks, since its already merged.
        - Addressed all comments from Krzysztof, Manivannan, Bjorn Helgaas.
          Specifically dropped defining a new macro for SLV_ADDR_SPACE_SZ.
          Letting it at reset value is fine.

          Both dt_binding_check and dtbs_check passed and tested on ipq9574-rdp433

	- Dropped the phy driver and binding patches as they have been
	  posted as a separate series.
	- Dropped the pinctrl binding fix patch as it is unrelated to the series
	  dt-bindings: pinctrl: qcom: Add few missing functions.
	- Rebased on linux-next/master.
	- Detailed change logs are added to the respective patches.
