drm: bridge: dw-hdmi: add ASoC dependency

The newly added sound driver depends on SND_SOC_HDMI_CODEC, which in
turn only makes sense when ASoC is enabled, as shown by this warning:

warning: (DRM_MSM && DRM_STI && DRM_MEDIATEK_HDMI && DRM_I2C_NXP_TDA998X && DRM_DW_HDMI_I2S_AUDIO) selects SND_SOC_HDMI_CODEC which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC)

Since the audio driver is probably useless without the audio subsystem,
adding a dependency here seems the right solution.
