Restores the audio functionality that was broken
since Linux version 6.6.y by adding the missing probe
functions for the player and reader components.

Specifically, the probe function in `sound/soc/sti/sti_uniperif.c:415` is being replaced by another probe function located at `sound/soc/sti/sti_uniperif.c:453`, which should instead be derived from the player and reader components. My patch correctly reinserts the missing probe entries, restoring the intended functionality.
The patch modifies the following files:
- `sound/soc/sti/sti_uniperif.c`: Changes the visibility of `sti_uniperiph_dai_probe` to non-static.
- `sound/soc/sti/uniperif.h`: Adds the declaration of `sti_uniperiph_dai_probe`.
- `sound/soc/sti/uniperif_player.c`: Adds `probe` function to `uni_player_dai_ops`.
- `sound/soc/sti/uniperif_reader.c`: Adds `probe` function to `uni_reader_dai_ops`.
This ensures the correct `probe` functions are utilized, thus fixing the audio regression.
