A default resolution in the ssd130x driver isn't set to an arbitrary 96x16
anymore. Instead is set to a width and height that's controller dependent.
The datasheets for the chips describes the following display resolutions:
- SH1106: 132 x 64 Dot Matrix OLED/PLED
- SSD1305: 132 x 64 Dot Matrix OLED/PLED
- SSD1306: 128 x 64 Dot Matrix OLED/PLED
- SSD1307: 128 x 39 Dot Matrix OLED/PLED
- SSD1309: 128 x 64 Dot Matrix OLED/PLED
Update DT schema to reflect what the driver does and make its users aware.
