Changes in v7:
- Add Reviewed-by tag of Rob Herring

Changes in v6:
- Add deprected to the compatible string and attn-gpios
  property
- Put const 0x2a i2c address for reg property only in case
  of not eeti,exc3000-i2c.
- Put false the attn-gpios property in case of not
  eeti,exc3000-i2c..
- Drop example for eeti,exc3000-i2c.

Changes in v5:
- Move bindings into eeti,exc3000.yaml
- Remove eeti.yaml

Changes in v2:
- Added in v2
