There is no reason this should be disabled by default. No external (per
board) configuration is needed and by default SoC components should be
enabled if they do not need anything from the board.

For soundwires disabling makes sense - these are busses so they need to
be explicitly enabled and populated with children.

vamacro needs supply from the board so this one also makes sense.
