soundwire: intel_ace2x: use legacy formula for intel_alh_id

Browse Source 
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.
