media: platform: mtk-mdp3: chip config split about pipe info

In MDP3, a pipe is used to represent a data path which
consisting of different components and MUTEX, as shown in
the following diagram:

                     +----------------------------+
                     |           MUTEX [*1]       |
                     +----------------------------+
                        S ^ S ^  S ^  S ^  S ^
                        | | | |  | |  | |  | |

[*1] MUTEX is SOF/EOF signal controller
[*2] S = Start of frame (SOF)
[*3] E = End of frame (EOF)
[*4] B = frame buffer

More pipes will be introduced in future chips for applications such as
higher frame rate frequency, which should integrate and reorder related
information into specific chip config file.
