overlays: Add ssd1306-spi, ssh1106-spi, ssd-1351-spi
Add overlays for SSD1306, SH1106 and SSD1351 based OLED displays. SH1106 is present in many 1.3 inch OLEDs and SSD1351 is present in 1.5 inch RGB OLEDs from AliExpress. This will load the staging fbtft drivers. Signed-off-by: Michael Kaplan <[email protected]>
