drm/i915: Provide more information on DP AUX failures
We're seeing some failures where an aux transaction still shows as
'busy' well after the timeout limit that the hardware is supposed to
enforce. Improve the error message so that we can see exactly which aux
channel this error happened on and what the status bits were during this
case that isn't supposed to happen.
v2:
- Make timeout a const variable so that the timeout & message will
match if we decide to change it in the future. (Lucas)
- Don't bother testing intel_dp->aux.name for NULL. (Lucas)
