ASoC: Intel: avs: Machine boards and HDA codec support

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>
From there on is a range of boards appended. All of them follow the same:

This series focuses on populating boards/ subdirectory with supported
configurations by the avs-driver. Note: it is independent of recently
provided "Driver code and PCM operations" series [1], that is, code
found here should not collide with it.

Series starts with a small change that adds a helper to sound pcm
header, allowing for retrieving string naming a direction without the
need of substream pointer. Said helper is used by codec driver code that
follows it but I believe it's generic and helpful enough that it can be
called an independent addition to the sound core.

Code for generic HD-Audio codec driver follows. It is a ASoC wrapper for
existing HD-Audio codec code found in sound/pci/hda/. There is basically
no custom logic involved up to the point that driver follows
HDA_DEV_LEGACY convention, rather than the HDA_DEV_ASOC one. Commit
message for the given patch iterates on this and explains crucial parts
of the implementation.

From there on is a range of boards appended. All of them follow the same
scheme:

- define avs_create_dai_link() so DAI-LINKs can be created dynamically,
  based on the link_mask (I2S) or the number of entries in the
  ->pcm_list_head list (HDA)
- define avs_create_dapm_routes() so DAPM routes can be created
  dynamically, same rules as above apply
- define probe() function that creates new ASoC card, assign all
  required operations and resources along with calling the two above

Changes in v2:
- 'link_mask' usage replaced with 'i2s_link_mask' as requested by
  Pierre
- 'ssp_test' board renamed to 'i2s_test' to match naming convention used
  for other i2s machine boards
- enriched commit message and Kconfig for the 'HD-Audio codec driver'
  patch as requested by Kai
