This helper function returns bitmask of SSP ports which support
specific direction according to endpoint descriptors. Smart
amplifier's render feedback does not count when finding SSP ports with
capture direction so caller could use this function to find out which
port is for headset(both render and capture) and which port is for
speakers(render only).

Add new fields to snd_soc_acpi_mach_params structure to provide
machine drivers SSP port mask of BT sideband device, render device,
and capture device. Machine driver could use the information to
detect the port number of headset, speaker, and BT offload devices.

With bitmasks from NHLT table, we could detect the port number of
headset, speakers, and bt offload. Here we assume a headset supports
both render and capture direction and speakers support render
direction only. BT offload has its own device type so we don't need to
check direction field in the NHLT endpoint descriptor.
