alarm/xbmc-imx bump; add alsa config

Rebuild to latest version.
They removed the imx-specific audio parts from the source which makes it necessary to configure alsa correctly. @pepedog recommended to add those configs to this package (see xbmc-imx6/xbmc#68).
Alternatively, this conf files could be added to the respective kernels.

I built this version and audio worked fine. I was not able to test passthrough though (missing the hardware).

As far as I know, this does not enable hd-audio. Unfortunately, I can not test this. If someone has the necessary hardware and wants to give it a trym just contact me.

Cheers
