[PATCH] ASoC: mediatek: mt8195: Re-add codec entry for ETDM1_OUT_BE dai link

[Chen-Yu Tsai]

This partially reverts commit e70b8dd26711704b1ff1f1b4eb3d048ba69e29da.

Said commit removes the codec entry for the ETDM1_OUT_BE dai link for
some reason. This does not have the intended effect, as the remaining
DAILINK_COMP_ARRAY(COMP_EMPTY()) platform entry becomes the codec
entry, and the platform entry is completely gone.

This causes in a KASAN out-of-bounds warning in mtk_soundcard_common_probe()
in sound/soc/mediatek/common/mtk-soundcard-driver.c:

	for_each_card_prelinks(card, i, dai_link) {
		if (adsp_node && !strncmp(dai_link->name, "AFE_SOF", strlen("AFE_SOF")))
			dai_link->platforms->of_node = adsp_node;
		else if (!dai_link->platforms->name && !dai_link->platforms->of_node)
			dai_link->platforms->of_node = platform_node;
	}

where the code expects the platforms array to have space for at least one entry.

Re-add the entry so that dai_link->platforms has space.
