Maybe when the cable is disconnected the DP phy should be shutdown and
some bit in the phy could effectively "cut off" the aux channel and then
NAKs would start coming through here in the DP controller I/O register

Initialize audio_comp when audio starts and wait for audio_comp at
dp_display_disable(). This will take care of both dongle unplugged
and display off (suspend) cases.
Changes in v2:
-- add dp_display_signal_audio_start()
Changes in v3:
-- restore dp_display_handle_plugged_change() at

Respect DRM's kconfig setting for fbdev console emulation. If enabled,
it will select all required config options. So remove them from vmwgfx's
Kconfig file.

While working on the recent aperture helpers, I found it hard to
disable fbdev because drivers keep on selecting it automatically.
Cleanup the config dependencies. Fbdev support should be configured
by users. DRM drivers should check for DRM_FBDEV_EMULATION to enable
fbdev support.
