dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845

Add interconnect properties such as interconnect provider specifier
, the edge source and destination ports which are required by the
interconnect API to configure interconnect path for MDSS.

Changes in v2:
	- None

Changes in v3:
	- Remove common property definitions (Rob Herring)

Changes in v4:
	- Use port macros and change port string names (Georgi Djakov)

Changes in v5-v7:
	- None

- #address-cells: number of address cells for the MDSS children. Should be 1.
- #size-cells: Should be 1.
- ranges: parent bus address space is the same as the child bus address space.
- interconnects : interconnect path specifier for MDSS according to
Documentation/devicetree/bindings/interconnect/interconnect.txt. Should be
2 paths corresponding to 2 AXI ports.
- interconnect-names : MDSS will have 2 port names to differentiate between the
2 interconnect paths defined with interconnect specifier.
Optional properties:
- assigned-clocks: list of clock specifiers for clocks needing rate assignment
