intel_adsp: ace20_lnl: add ALH DAI support

Browse source 
Add missing definitions for ALH DAIs. Keep the same FIXME
reminder in the comments we have for ACE1.5 that explains
the background of these definitions.

/*
* FIXME this is modeling individual alh channels/instances
* with node labels, which has problems. A better representation
* is discussed here:
*
* https://github.com/zephyrproject-rtos/zephyr/pull/50287#discussion_r974591009
*
* The hardware actually supports 16 ALH streams/FIFOs. Below description does
* not fully represent hardware capabilities and is expected to be modified.
