Subject: [PATCH v2 2/4] dt-bindings: display: ssd1307fb: Add entry for SINO WEALTH SH1106

From: Chen-Yu Tsai <wens@...e.org>

The SINO WEALTH SH1106 is an OLED display driver that is somewhat
compatible with the SSD1306. It supports a slightly wider display,
at 132 instead of 128 pixels. The basic commands are the same, but
the SH1106 doesn't support the horizontal or vertical address modes.

Add a compatible string for it.
