Subject: [PATCH v4 3/5] drm/solomon: Add ssd130x new compatible strings and deprecate old ones.

The current compatible strings for SSD130x I2C controllers contain an "fb"
and "-i2c" suffixes. These have been deprecated and more correct ones were
added, that don't encode a subsystem or bus used to interface the devices.
