Bespoke trigger support was added when Linux v3.5 by this patch.
commit 07bf84aaf736781a283b1bd36eaa911453b14574
("ASoC: dpcm: Add bespoke trigger()")
test-component driver is using it, but this is because it indicates used
function for debug/trace purpose. Except test-component driver, bespoke
trigger has never been used over 10 years in upstream.
We can re-support it if needed in the future, but let's remove it for now,
because it just noise in upstream.
