The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

We already have dummy-codec, dummy-platform.
But its issues are
1) we don't have dummy-cpu,
2) we can't select it via DeviceTree
3) It do nothing
Sometimes we want to have Dummy Sound Component for debugging,
for testing, for learning Framework behavior, etc, etc...
This patch adds Test-Component driver for it.
User can select CPU Component by using "test-cpu" compatible,
and can select Codec Component by using "test-codec" compatible.
It doesn't support Platform so far, but is easy to add.
We can verbose print to know its progress if user selected
xxx-verbose compatible driver.
for example,
test-cpu : silent Component, silent DAI
test-cpu-verbose-component : verbose Component, silent DAI
test-cpu-verbose-dai : silent Component, verbose DAI
test-cpu-verbose : verbose Component, verbose DAI
