ANDROID: GKI: fix build error on 32bits due to ASoC msm change 



Commit dbad92f6 ("ANDROID: GKI: ASoC: msm: fix integer overflow for
long duration offload playback") causes a link error if the kernel is
built for a 32bit target, like i386.

The error is::
	ERROR: "__umoddi3" [sound/soc/intel/atom/snd-soc-sst-atom-hifi2-platform.ko] undefined!
	kernel/scripts/Makefile.modpost:108: recipe for target '__modpost' failed

Fix this problem up by doing the division with the internal kernel
function to do so.
