[PATCH 5.4 223/434] ASoC: SOF: imx: fix reverse CONFIG_SND_SOC_SOF_OF dependency

[Greg Kroah-Hartman]

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

[ Upstream commit f9ad75468453b019b92c5296e6a04bf7c37f49e4 ]

updated solution to the problem reported with randconfig:

CONFIG_SND_SOC_SOF_IMX depends on CONFIG_SND_SOC_SOF, but is in
turn referenced by the sof-of-dev driver. This creates a reverse
dependency that manifests in a link error when CONFIG_SND_SOC_SOF_OF
is built-in but CONFIG_SND_SOC_SOF_IMX=m:

sound/soc/sof/sof-of-dev.o:(.data+0x118): undefined reference to `sof_imx8_ops'

use def_trisate to propagate the right settings without select.

Fixes: f4df4e4042b0 ("ASoC: SOF: imx8: Fix COMPILE_TEST error")
Fixes: 202acc565a1f ("ASoC: SOF: imx: Add i.MX8 HW support")
