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 (e.g. nocturne that wants to provide DMIC properties to OS) 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 codec 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 is the only board enabling HDA codec initialization using common block code. 4. Selects original config SOC_INTEL_COMMON_BLOCK_HDA for skylake SoC. Above changes need to be bundled and pushed in as a single change in order to avoid breaking existing users.
