Does all QCS6490 boards with AudioReach have these two (4?) DMICs? Is
this board-specific or generic?

Does these settings belong in the SoC description? Are they fixed for
all targets of sc7280, or are there any board-specific variations? Any
variations based on which audio solution the board implements?

yes, all QCS6490 boards are with default 4-DMICs.

yes, these configs are fixed for all the variants of sc7280. These are 
on-SoC configs and don't change with variants.
