dt-bindings: display: ssd1307fb: Add entry for SINO WEALTH SH1106

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.
