mb/google/fatcat/var/francka: Conditionally init HDA

This commit implements `mainboard_hda_init()` for the Google Francka
mainboard variant. This overrides the default weak HDA common
initialization.

Initialization of the High Definition Audio (HDA) controller, managed by
`azalia_audio_init()` (which handles HDA verb table loading), is now
conditional. It proceeds only if the firmware config
`FW_CONFIG(AUDIO, AUDIO_ALC256M_CG_HDA)` is set. This targets the
ALC256M-CG HDA codec.

This change ensures that HDA verb tables are loaded only when the
ALC256M-CG HDA codec is actively configured for the Francka variant.
Crucially, this prevents attempts to incorrectly load HDA verbs for
other audio interfaces, like SoundWire (SNDW), which might be present
in different Francka hardware configurations.

The headers `device/azalia_device.h` and `intelblocks/hda.h` are added
to support this HDA initialization logic.

BUG=b:ENTER_FRANCKA_BUG_ID_HERE
TEST=Verified HDA verb table loading is skipped on Francka platforms
     when configured with non-HDA audio codecs (e.g., SNDW),
     and proceeds as expected when ALC256M-CG HDA is configured
