Subject: [PATCH] Fix contrast and display mode initialisation

The double byte command OLED_CMD_SET_CONTRAST (SSD1306 datasheet rev 1.1 p.28) was followed by display_mode.
So the contrast was set to 0xA6 or 0xA7 depending on the display mode configured and the display mode itself wasn't configurable.
