[PATCH] drm/radeon/kms: only enable underscan by default if the monitor supports audio

[Alex Deucher]

Users with TVs or monitors that don't overscan by default would prefer
to not have underscan enabled, while users with overscanning TVs prefer
underscan.  This should hopefully make everyone happy as most monitors
with audio tend to be TVs which overscan by default and monitors without
audio don't overscan.  Underscan can still be overriden by changing the
connector attribute.
