Tidy app_usb_audio_awe - Githubissues

Hi Guys, this is still WIP but contains some important changes like brining in sw_usb_audio (and track it's deps). The reason for this is two fold:

Remove audiohw setup from local apps
Utilise UA test infrastructure

It'd be good to get this merged and then I will re-open this PR with further app tidying items but also it helps me get on with https://github.com/xmos/lib_awe/pull/17
