pcm: Add sw_params API functions to get/set timestamp type

Browse source 
For obtaining / changing the timestamp type, add the corresponding
sw_params accessor API functions together with the public definitions
of timestamp types.

This patch only adds the functions and defines but doesn't bring the
functional changes yet.
