[PATCH v3] drm/i2c: tda998x: Deprecate "nxp,tda998x" in favour of "nxp,tda9989"

[Jean-Francois Moine <moinejf@free.fr>]

The tda998x driver accepts only 3 chips from the TDA998x family.

To avoid confusion with the other TDA998x chips, this patch changes
the driver compatible string to "nxp,tda9989".

As the previous compatible string is not actually used in any DT,
no compatibility is offered.

v3:
  - fix the I2C ID (the OF compatible is not used for such drivers)
  - define only one compatible (Sebastian Hesselbarth)
  - change the subject (Sebastian Hesselbarth)
v2:
  - change the subject to drm/i2c
This patch applies after
