[PATCH 1/2] ASoC: meson: card: leave the device drvdata to the ASoC card

[Jerome Brunet]

snd_soc_register_card() sets the device drvdata to the card, so
meson_card_remove() gets the card, not the meson_card it expects. The
card is not the first member of meson_card, so the links are read from
the wrong place and remove() crashes on unbind or rmmod.

Get priv from the card and drop the platform_set_drvdata() call that
the card registration overrides.

Fixes: aa9c3b7273a5 ("ASoC: meson: axg: extract sound card utils")
