[alsa-devel] [PATCH 3/3] ASoC: hdac_hdmi: Drop support for Icelake

[Pierre-Louis Bossart]

From: Kai Vehmanen <kai.vehmanen at linux.intel.com>

This reverts commit 019033c854a2 ("ASoC: Intel: hdac_hdmi:
add Icelake support").

Icelake HDMI audio is supported by the HDMI codec driver,
which can be used both in non-DSP (legacy HDA) and with
DSP (SOF) configurations.
