ASoC: hdmi-codec: only startup/shutdown on supported streams

BugLink: https://bugs.launchpad.net/bugs/2016878
[ Upstream commit e041a2a550582106cba6a7c862c90dfc2ad14492 ]

Currently only one stream is supported. This isn't usally a problem
until you have a multi codec audio card. Because the audio card will run
startup and shutdown on both capture and playback streams. So if your
hdmi-codec only support either playback or capture. Then ALSA can't open
for playback and capture.

This patch will ignore if startup and shutdown are called with a non
supported stream. Thus, allowing an audio card like this:

           +-+
 cpu1 <--@-| |-> codec1 (HDMI-CODEC)
           | |<- codec2 (NOT HDMI-CODEC)
           +-+
