Fangzhi Zuo c7720f23bb drm/amd/display: Ignore First MST Sideband Message Return Error
[ Upstream commit acea108fa0 ]

[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.

v2: squash in additional DMI entries
v3: squash in static fix
