ARM: dts: msm: enable imgswap on sharp nt35597 dual panel
Fix stride corruption issue due to panel portswap observed when
some video layers cross panel split boundaries. Fix is to
initialize panel with the imgswap feature enabled, and then
modify the DSI CTRL horizontal tiling mapping to undo the swap.
