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 support for this display driver. The default values for some of
the hardware settings are taken from the datasheet.
