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 v2:
	- changed the logic for getting speed and width as suggested
	 by bjorn.
	- fixed compilation errors.
