[PATCH 03/22] drm/amd/display: No display after resume from WB/CB

[brichang]

From: Tsung-hua Lin <tsung-hua....@amd.com>

[why]
First MST sideband message returns AUX_RET_ERROR_HPD_DISCON
on certain intel platform. Aux transaction considered failure
if HPD unexpected pulled low. The actual aux transaction success
in such case, hence do not return error.

[how]
Not returning error when AUX_RET_ERROR_HPD_DISCON detected
on the first sideband message.
