This adds a driver for the Waveshare 4.2-inch e-Paper Module V2. This revision is incompatible with the existing epd4in2 driver because it uses the SSD1683 display controller.

The implementation is based on Waveshare's official C driver and existing drivers in this repository.

The driver supports full, partial, and quick refresh modes. Combining quick and partial refresh is currently unsupported because this behavior is not defined by Waveshare's reference driver.
