[PATCH 3/6] ASoC: sigmadsp: Drop support support SIGMA_ACTION_DELAY

[Lars-Peter Clausen <lars@metafoo.de>]

The official firmware generation tool never emitted any SIGMA_ACTION_DELAY
instructions. Keeping support for it with the new restructured loader that
also supports v2 will be difficult, so drop support for it.
