drivers: ssd1306: fixup dts support

A few issues with the dts support for the SSD1306 display driver:
1. binding file mixed description & generation up together
   - rename most uses of generation to description and add proper
     generation field into yaml
2. Drop use of BASE_LABEL, this shouldn't be used by most bindings
3. dts defines that are being assumed in driver aren't correct.  We
   should be using a dts_fixup.h in the sample to map the generated
   defines to those used in the driver.  We remove the incorrect
   defines that the driver assumes right now.
4. Fixup 'segment-remap' and 'com-invdir' properties that are booleans
   in the binding file and associated code changes.
