HW constraints are implemented to reflect the hardware limitation on BDW platform. Changes since v1: - Change the patch title. - Remove the DUAL_CHANNEL and QUAD_CHANNEL macros which are too obvious. - Follow the naming convertion, using 'bdw_rt5650_' and 'bdw_rt5677_' to name startup functions. - Refine the comments in startup functions. - Redesign the bdw_rt5650_fe_startup() function for readability. - Add an assignment to initialize runtime->hw.channels_max variable.
