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.
