[meta-intel] [PATCH 1/1] chiefriver: provide ALSA device configuration for NUC

[nitin.a.kamble at intel.com]

From: Nitin A Kamble <nitin.a.kamble at intel.com>

The NUC routes audio through HDMI. The default ALSA config
is failing to provide working sound. And this configuration
file configures ALSA system to use HDMI-0 port for audio out.
