[PATCH v2] dt-bindings: display: Add Solomon SSD1351 OLED controller

[Amit Barzilai]

Add a device tree binding for the Solomon SSD1351, a 128x128 65k-color
RGB OLED display controller driven over a 4-wire SPI bus. The binding
builds on the shared solomon,ssd-common.yaml properties already used by
the other Solomon display controllers.

Changes since v1:
- Drop solomon,width / solomon,height: both are deducible from the
  compatible and are already declared (as optional) by the referenced
  solomon,ssd-common.yaml, so a local override is unnecessary.
- Drop the rotation property: it has no consumer (rotation is being removed from the driver).
- Use dt-bindings/gpio/gpio.h flag defines in the example
  (reset-gpios active-low, dc-gpios active-high).
