It's a dilemma of the default kconfig enablement.  In general we want
to keep the default disabled for leaf drivers.

CONFIG_SND_HDA_CODEC_REALTEK is still present but now it's a
menuconfig, so this is taken over from the previous config.  The
remaining CONFIG_SND_HDA_CODEC_ALC* are the missing stuff.
Maybe we should set CONFIG_SND_HDA_CODEC_ALC*=y as default as an
exception for smooth upgrade?

I guess the same applies to the HDMI audio stuff, too.
