[PATCH 07/21] ASoC: Intel: board_helpers: support sof_card_private initialization

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

From: Brent Lu <brent.lu@xxxxxxxxx>

Add a helper function for machine drivers to initialize common part of
sof_card_private structure. Also unify the macros of board quirks for
the initialization.
