ASoC: sti: add missing probe entry for player and reader

BugLink: https://bugs.launchpad.net/bugs/2083656

[ Upstream commit 6b99068d5ea0aa295f15f30afc98db74d056ec7b ]

This patch addresses a regression in the ASoC STI drivers that was
introduced in Linux version 6.6.y. The issue originated from a series of
patches (see https://lore.kernel.org/all/87wmy5b0wt.wl-kuninori.morimoto.gx@renesas.com/)
that unintentionally omitted necessary probe functions for the player
and reader components.

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.
This patch correctly reinserts the missing probe entries,
restoring the intended functionality.
