PCIe0, PCIe1, PCIe2, PCIe3 (and corresponding PHY) devices
are found on IPQ9574 platform. The PCIe0 & PCIe1 are 1-lane
Gen3 host whereas PCIe2 & PCIe3 are 2-lane Gen3 host.

This series adds support for enabling the same

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

Changes in V2:
	- Reordered the patches and splitted the board DT changes
	  into a separate patch as suggested
	- Detailed change logs are added to the respective patches
