Add support for the direct connection DPI found in MT8195 and MT8188 SoCs. Bonus in this series is the addition of support for the Pattern Generator found in the DPI HW: since I needed this for debugging during development, I had to code in the actual support bits and it looked like a waste of time to just remove it. I instead decided to clean it up and upstream it, as this will anyway come handy for multiple things, of which the most important (imo) are: - Adding support for new SoCs in the future will be less time consuming as this driver already has the pattern generator in; - CI Testing might be able to make use of this to validate that the data that comes out is not garbled (so, to help testing display support in an automated manner).
