Document support for the Okaya RH128128T display, which is a 128x128
1.44" TFT display driven by a Sitronix ST7715R TFT Controller/Driver.
ST7715R and ST7735R are very similar. Their major difference is that
the former is restricted to displays of up to 132x132 pixels, while the
latter supports displays up to 132x162 pixels.

While touching the bindings file, can I convince you to convert it to
meta-schema format (.yaml)?
@@ -4,7 +4,9 @@ This binding is for display panels using a Sitronix ST7735R controller in SPI
mode.
Required properties:
-- compatible: "jianda,jd-t18003-t01", "sitronix,st7735r"
+- compatible: Must be one of the following combinations:
+ - "jianda,jd-t18003-t01", "sitronix,st7735r"
+ - "okaya,rh128128t", "sitronix,st7715r"
It would be nice if there was a "description" for each pair of
compatible that identified the actual panel.
In your case "Okaya RH128128T 1.44" 128x128 TFT display"
It can be looked up in git history - but better to have it in the
binding file.

It would be nice to have the Adafruit part name in here too while we
are at it. I had to dig really deep to find what the actual display
panel was.
