[ros-diffs] [silverblade] 27494: Restructured PORTCLS as requested by Christoph_vW (so PREfast can be used.) Here is also a very bare-bones implementation of SysAudio (actually it just creates \Device\sysaudio and a symlink for now...)

Log:
Restructured PORTCLS as requested by Christoph_vW (so PREfast can be 
used.) Here is also a very bare-bones implementation of SysAudio 
(actually it just creates \Device\sysaudio and a symlink for now...)
