The Bay Trail SST-DSP firmware version looses track of all streams over a

This commit adds support for free-ing the streams on suspend and
re-allocating them on resume, fixing suspend/resume issues on devices
using this firmware version.
This new behavior gets triggered by a new flag in sst_platform_info which
only gets set on Bay Trail platforms.
This has been tested on the following devices:
-Asus T100TA, Bay Trail + ALC5642 codec
-Ployer MOMO7W, Bay Trail CR + ALC5652 codec

A nit, perhaps to fix multi line comment style as well?
The is the net/* style of multi-line comments which is used in quite a few
places in the sounds/soc dir. I think both styles are accepted under sound/soc?
