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.

	Change logs are added to the respective patches
	This series depends on the below series which adds support for
	Interconnect driver[1] and fetching clocks from the Device Tree[2]

	- 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.

	- Reordered the patches and split the board DT changes
	  into a separate patch as suggested
	- Detailed change logs are added to the respective patches
