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.
