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

 Changes in V5:
	- Dropped anoc and snoc lane clocks from Phy nodes and enabled them
	  via interconnect.
	- Dropped msi-parent as it is handled via msi IRQ

'pcie@' since this is a PCIe controller.

Are you sure that this platform only has single MSI SPI IRQ?

This comment is redundant.

Is this really the interconnect paths between PCIe-DDR and PCIe-CPU? I doubt...

It has 8 MSI SPI IRQs, will define all of them

We actually designed a minimalistic ICC driver for enabling the NoC 
clocks based on the suggestions received from the community.
Please find the link to the discussions that went in for introducing the 
ICC driver for NoC clock enablement
