    drm/panel: simple: Fix Innolux G101ICE-L01 timings
    
    [ Upstream commit 3f9a91b6c00e655d27bd785dcda1742dbdc31bda ]
    
    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.
