[PATCH] ASoC: meson: aiu-fifo.c: use devm_kzalloc(), and remove .remove function

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

Current aiu-fifo.c is using kzalloc()/kfree(), but we can replace
it by devm_kzalloc(), and remove kfree().
This patch do it.
