ALSA: hda/hdmi: Enable drivers as default

Like other HD-audio codec drivers, HD-audio HDMI codec driver was
split to multiple drivers, and now users are forced to choose the
right kconfig items.

For smoother upgrade path, keep the previous CONFIG_SND_HDA_CODEC_HDMI
as the meuconfig, so that the kconfig can be taken over from the
previous config.  The all belonging HDMI codec drivers are enabled as
default as long as CONFIG_SND_HDA_CODEC_HDMI is set.

This is only about the default config, and each driver can be still
disabled if user wants to reduce the size, too.

The kconfig for the generic HDMI driver is changed to
CONFIG_SND_HDA_CODEC_HDMI_GENERIC along with this action.
