ALSA: hda/cirrus: Enable drivers as default

Like HD-audio Realtek drivers, Cirrus Logic HD-audio codec driver was
split to multiple drivers, too, and now users are forced to choose the
right kconfig items.

For smoother upgrade path, keep the previous
CONFIG_SND_HDA_CODEC_CIRRUS as the menuconfig.

The new kconfig CONFIG_SND_HDA_CODEC_CS42* are enabled as default, as
long as CONFIG_SND_HDA_CODEC_CIRRUS is set, so that the system with
Cirrus codec can keep working.

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