Subject: [PATCH v4 0/2] Add PCIe support for IPQ5424

This series adds support for enabling the PCIe host devices (PCIe0,
PCIe1, PCIe2, PCIe3) found on IPQ5424 platform. The PCIe0 & PCIe1
are 1-lane Gen3 host and PCIe2 & PCIe3 are 2-lane Gen3 host.

Depends upon [1]

Changes in V4:
	- Dropped patch #1 because it is already part of the dependency series.
	- Dropped patch #2 because icc tags are required only for platforms
	  using icc-rpm or icc-rpmh. IPQ5424 doesn't use icc-rpm/icc-rpmh,
	  instead it uses icc_clk APIs to register with interconnect
	  provider.
	- dtsi
		- Added mhi register space in all pcie controller nodes.
		- Updated pcie nodes unit address to align with parf
		  register address space.
		- Moved msi-map before interrupts.
		- Rearrange nodes w.r.t. address sort order.
		- Dropped ICC tag from the interconnect paths.
		- Removed bus-range from all pcie controller nodes.
	- dts
		- Added a new line before status in pcie2 and pcie3
		  nodes.
		- Dropped 'output-low' property from pcie2-default-state
		  and pcie3-default-state nodes. 
	- Fixed all review comments from Konrad, Krzysztof.
