Subject: [PATCH 3/5] drm/solomon: Add ssd130x-i2c compatible strings without an -fb suffix

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 new ones that don't have
the -fb suffix. The old entries are still kept for backward compatibility.
