Michael Sevakis 2dd1f37a10 Fix f5a5b94 errors. Employ SW volume for select targets on SIM. 
Onda VX747 sim was missing a limits #define; #include limits.h in
pcm_sw_volume.h.

Simply use the software volume control for the SIM volume control
rather than the SDL volume control when the target would have it
natively.
