DRA7xx-EVM uses HDMI as the default pulseaudio sink
Description
dra7xx-evm exposes both HDMI and onboard analog audio cards. pulseaudio, by default, chooses alsa_output.platform-omap-hdmi-audio.0.auto.analog-stereo as the default sink which is not the desired default since we don't use an HDMI display with dra7xx-evm. The default sink should be set to alsa_output.platform-sound0.analog-stereo so that audio works OOTB.
