[PATCH 1/5] ASoC: meson: axg-card: set link name based on link node name

[Jerome Brunet]

So far the link names of the axg sound card was derived from the cpu name
of the link. Since the dai link must be unique, it works as long as a
device does not provide more than one cpu dai. However, the 'tohdmitx'
does provide 2 dais used as cpu on codec-to-codec links

Instead of cpu name, use the node name of the dai link. DT already enforce
the uniqueness of this name
