This fixes a memory corruption when ASoC devices are used in full-duplex mode. Specifically for pxa-ssp code, where this pointer is dynamically allocated for each direction and destroyed upon each stream start.
All other platforms are fixed blindly, I couldn't even compile-test them. Sorry for any breakage I may have caused.

I indeed missed quite a few platforms, you were right. Hope I got them all now. Better check again - thanks!
