lambdaconcept_ecpix5: Add initial Video support at 640x480 (with Terminal/Framebuffer).
I2C intialization code adapted from https://github.com/ultraembedded/ecpix-5.
Tested with:
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-terminal --build --load
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-framebuffer --build --load
