Subject: [PATCH v1] drm/msm/dp: assign correct DP controller ID to interface table
At current x1e80100 interface table, interface #3 is wrongly
connected to DP controller #0 and interface #4 wrongly connected
to DP controller #2. Fix this problem by connect Interface #3 to
DP controller #0 and interface #4 connect to DP controller #1.
Also add interface #6, #7 and #8 connections to DP controller to
complete x1e80100 interface table.
