drivers/video: add support for the Solomon SSD1307 OLED Controller
Add support for the Solomon SSD1307 OLED controller found on the Crystalfontz CFA10036 board. This controller can drive a display with a resolution up to 128x39 and can operate over I2C or SPI. The current driver has only been tested on the CFA-10036, that is using this controller over I2C to driver a 96x16 OLED screen.

+* Solomon SSD1307 Framebuffer Driver
+
+Required properties:
+ - compatible: Should be "solomon,ssd1307fb-<bus>". The only supported bus for
+ now is i2c.
+ - reg: Should contain address of the controller on the I2C bus. Most likely
+ 0x3c or 0x3d
+ - pwm: Should contain the pwm to use according to the OF device tree PWM
+ specification [0]
+ - reset-gpios: Should contain the GPIO used to reset the OLED display
+
+Optional properties:
+ - reset-active-low: Is the reset gpio is active on physical low?
