ALSA: x86: hdmi: select CONFIG_SND_PCM

The newly added driver uses the PCM helpers and fails to link if they are disabled: sound/built-in.o: In function `hdmi_lpe_audio_runtime_suspend': intel_hdmi_audio.c:(.text+0x15906): undefined reference to `snd_pcm_suspend' sound/built-in.o: In function `had_pcm_hw_params': intel_hdmi_audio.c:(.text+0x15ac7): undefined reference to `snd_pcm_lib_malloc_pages' sound/built-in.o: In function `had_pcm_open': intel_hdmi_audio.c:(.text+0x15d49): undefined reference to `snd_pcm_hw_constraint_integer' This uses a Kconfig 'select' statement to make sure they are enabled.
