From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
Starting with Lunar Lake, the notion of ALH is mostly irrelevant, since the HDaudio DMAs are used. However the firmware still relies on an 'ALH gateway' with a 'node_id' based on the same formula.
This patch in isolation has no functional impact, it's only when the ASoC parts use it that we will see a changed behavior.
