Change in coreboot[master]: soc/intel/.../hda: Add and use config for initialization of HDA codecs

by Furquan Shaikh (Code Review)

Furquan Shaikh has uploaded this change for review. ( https://review.coreboot.org/28806 Change subject: soc/intel/.../hda: Add and use config for initialization of HDA codecs ...................................................................... soc/intel/.../hda: Add and use config for initialization of HDA codecs Config option SOC_INTEL_COMMON_BLOCK_HDA is currently used for initialization of HDA codecs only. This prevents adding of any static devices under the HDA device node. However, there can be boards which want to add devices under HDA node without performing any codec initialization using the HDA. This change: 1. Adds a new config option SOC_INTEL_COMMON_BLOCK_HDA_VERB that can be set explicitly by the boards that want to perform code initialization. 2. Uses newly added config option is used to guard the initialization functions for the codec. Rest of the device operations can still be used by all the other boards without having to use HDA codec initialization. 3. Selects the newly added option SOC_INTEL_COMMON_BLOCK_HDA_VERB in kblrvp which was the only board enabling HDA codec initialization using common block code. 4. Original config SOC_INTEL_COMMON_BLOCK_HDA is selected for skylake SoC. Above changes need to be bundled and pushed in as a single change in order to avoid breaking existing users.
