[PATCH 6/8] ASoC: audio-graph: let dai_link->init be overridable

[luca.ceresoli@bootlin.com]

From: Luca Ceresoli <luca.ceresoli@bootlin.com>

We can already override dai_link->ops via a custom pointer in
asoc_simple_priv. Do the same for dai_link->init.

This is needed for a card that need to call .set_sysclk multiple times to
initialize more than one clock. The current code does not allow to do it
cleanly.
