[PATCH 1/5] dt-bindings: display: ssd1307fb: Deprecate fbdev compatible strings

[Javier Martinez Canillas]

The current compatible strings for SSD130x I2C controllers contain an -fb
suffix, this seems to indicate that are for a fbdev driver. But the DT is
supposed to describe the hardware and not Linux implementation details.

Let's deprecate those compatible strings and add a new enum that contains
compatible strings that don't have a -fb suffix. These will be matched by
the ssd130x-i2c DRM driver.
