No Audio over DisplayPort
Submitted by StefanBruens

Currently audio is not supported when DP is used for connecting the monitor.
This works if the monitor is connected using HDMI, or when fglrx is used.
I tried patching the driver with hardcoded values taken from the fglrx drivers using radeontool, unfortunately, this was not sufficient.
- added call in atombios_encoders.c:radeon_atom_encoder_mode_set(...) to initialize audio when encoder mode is DP.
- patched evergreen_hdmi.c:evergreen_hdmi_enable(...) and evergreen_hdmi_setmode(...) to set same register values as fglrx.
- patched dce6_afmt.c to set values matching fglrx.
Something is missing here ...
