  1. drivers: display: Add ssd1322 driver 

    Initial support for SSD1322 OLED display driver. Only 1 bit color mode is
supported.

Most options map directly to values documented in the datasheet,
except segments-per-pixel, which I had to add to support the Newhaven
NHD-2.7-12864WDW3. This is a slightly odd feature, but in practice
it is a lot nicer to support it in the driver, and since we're currently
remapping pixels anyway, it makes sense to implement here.

This driver also has a configurable buffer size for the pixel conversion.
By using a larger buffer, we can potentially use DMA for the SPI transfer.
The default is set to 8, which is the smallest value that supports
segments-per-pixel = 2
