[PATCH v2 5/9] media: platform: mtk-mdp3: chip config split about resolution limitations

[Moudy Ho <moudy.ho@xxxxxxxxxxxx>]

Due to differences in hardware design, the supported max and min
resolutions and scaling capabilities will vary, and should be
moved and integrated into the chip configuration header file.
