dt-bindings: exynos_dsim: update of graph bindings 



Of-graph bindings should describe ports present in the device, not the
devices it can be connected to. The patch replaces verbose description
with shorter but more precise one. While at it clock related properties
are moved to the main node as it is their actual location.

Video interfaces:

  Device node can contain video interface port nodes according to [2].

  The following are properties specific to those nodes:



  port node inbound:

    - reg: (required) must be 0.

  port node outbound:

    - reg: (required) must be 1.



  endpoint node connected from mic node (reg = 0):

    - remote-endpoint: specifies the endpoint in mic node. This node is required

		       for Exynos5433 mipi dsi. So mic can access to panel node

		       throughout this dsi node.

  endpoint node connected to panel node (reg = 1):

    - remote-endpoint: specifies the endpoint in panel node. This node is

		       required in all kinds of exynos mipi dsi to represent

		       the connection between mipi dsi and panel.

  0: RGB input,

  1: DSI output
