MLK-12425-2 video: epdc: introduce epdc support
Support EPDC. E-Ink feature is supported by i.MX6DL/SL/SLL/ULL and i.MX7D. This driver supports user defined logo file, if there is no logo file, it will draw a black border around a white screen. If need to enable EPDC, a waveform file is required to let all work. Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME support. Please refer to Linux Reference Manual for how to flash WAVEFORM file.
