qv4l2: enable the play action on non-streaming radio rx

The commit 37f42eb35d87 ("qv4l2: reorganize colorspace handling")
disabled the play action on non-streaming devices.

This patch enables the play action 'm_capStartAct' on non-streaming
radio rx (audio-only) devices, assuming that 'isCapture' should exclude
radio tx. In addition, it also disables the step-frame action
'm_capStepAct' on radio devices.
