hal: Fix backend configuration during stream switch
-Currently, input stream sample rate and/or bit width is compared
with current backend sample rate and/or bit width. Backend is
re-configured only if input stream's rate/width is higher. This
causes incorrect sampling rate during stream switch of varying
sample rates.
-The backend is configured at highest bit width and/or sample rate
amongst all active playback usecases.
-By setting the backend re-configuration flag only when the selected
sample rate and/or bit width differ with current backend sample rate
and/or bit width, re-routing is enabled and backend is re-configured.
-Exception: 16 bit playbacks is allowed through 16/48 backend only.
-Enable logs for app type, acdb id and sample rate.
