  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 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.
