The Innolux G101ICE-L01 datasheet [1] page 17 table
6.1 INPUT SIGNAL TIMING SPECIFICATIONS
indicates that maximum vertical blanking time is 40 lines.
Currently the driver uses 29 lines.
Fix it, and since this panel is a DE panel, adjust the timings
to make them less hostile to controllers which cannot do 1 px
HSA/VSA, distribute the delays evenly between all three parts.
