[PATCH v3 1/3] dt-bindings: PCI: qcom: ep: Add interconnects path

[Krishna chaitanya chundru]

Some platforms may not boot if a device driver doesn't initialize
the interconnect path. Mostly it is handled by the bootloader but
we have starting to see cases where bootloader simply ignores them.

Add the "pcie-mem" interconnect path as a required property to the
bindings.
