  Add basic support for managing "pcie-mem" interconnect path by setting
a low constraint before enabling clocks and updating it after the link
is up based on link speed and width the device got enumerated.

changes from v9:
	- addressed the comments by mani.
changes from v8:
        - Added cpu to pcie path in dtsi and in dtsi binding.
changes from v7:
        - setting icc bw to '0' in disable resources as suggested by mani.
changes from v6:
        - addressed the comments as suggested by mani.
changes from v5:
        - addressed the comments by mani.
changes from v4:
        - rebased with linux-next.
        - Added comments as suggested by mani.
        - removed the arm: dts: qcom: sdx55: Add interconnect path
          as that patch is already applied.
changes from v3:
        - ran make DT_CHECKER_FLAGS=-m dt_binding_check and fixed
         errors.
        - Added macros in the qcom ep driver patch as suggested by Dmitry
changes from v2:
        - changed the logic for getting speed and width as suggested
         by bjorn.
        - fixed compilation errors.

Krzysztof, can this series be merged for 6.6? Bjorn A will pick the dts patches.
