drm/mediatek: dpi: Add dp_intf support
Dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code. This patch adds support for mt8195-dpintf to this dpi driver. Main differences are: - 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one iteration. - Input of dp_intf is two pixels per iteration. - Some register contents differ slightly between the two components.
