mb/prodrive/hermes: Configure 'internal audio'
Implement `mainboard_azalia_program_runtime_verbs` to configure the Realtek ALC888 codec according to the settings in the EEPROM. The encoding of the `internal_audio_connection` field is: 0: Disabled 1: Front HP out 2: Internal speaker Change-Id: I5e0013217838888977aaa9259e0cfb78c82f719f Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/50389 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>
