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.

DTS patch is based on the below series
https://lore.kernel.org/linux-arm-msm/20230329053726.14860-1-quic_kathirav@quicinc.com/

Changes in V3:
	- 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.
	
Changes in V2:
https://lore.kernel.org/linux-arm-msm/20230404164828.8031-1-quic_devipriy@quicinc.com/
	- Reordered the patches and splitted the board DT changes
	  into a separate patch as suggested
	- Detailed change logs are added to the respective patches
