alarm/{firmware-imx,imx-vpu,libfslvpuwrap} update to 3.10.31-beta release

This updates the freescale libraries imx-vpu and libfslvpuwrap to the newese -beta release.
It also updates the firmware needed for the vpu to the newest -beta release.

I've been running this for quite some time now and I have had better results with those beta versions than I have ever had with the ga ones. While I have not experienced any performance changes, they seem to be much more stable.

I suggest to merge this along with / before archlinuxarm/PKGBUILDS#1040.

Happy holidays!
