Subject: [PATCH 1/2] media: i2c: tda1997x: constify
 snd_soc_component_driver struct

`tda1997x_codec_driver` is not modified after its declaration, and it
is only passed to `devm_snd_soc_register_component()`, which expects
a constant `snd_soc_component_driver`.

Move `tda1997x_codec_driver` to a read-only section by declaring it
const.
