dmesg: miniDP-to-VGA cause machine boot up with "ERROR"
Environment:

Kernel: (drm-intel-next-queued)da66146425c3136943452988afd3d64cd551da58

drm/i915: include hangcheck action and score in error_state
lspci:
--------------------
00:02.0 VGA compatible controller: Intel Corporation Device 0162 (rev 09)
Description:
--------------------
When machine boot up with miniDP-to-VGA, there's "Error" in dmesg. I have tried
many older kernels, and can't find a good commit.
Both -next-queued and -fixes branches reproducible.
Other IVB machines like desktop and mobile haven't come up such issue.
Other display adapter like miniDP-to-DVI/DP/HDMI work well.
Test Step:
--------------------
1. plugged in miniDP-to-VGA
2. reboot machine
3. check dmesg
Error type:
-------------------
[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up</pre>
