drm/exynos: decon: Add support for DECON-EXT
* Modify DECON-INT driver to support DECON-EXT.
* Add a table of porch values needed to set timing registers of DECON-EXT.
* DECON-EXT supports only H/w Triggered COMMAND mode.
* DECON-EXT supports only one DMA window(window 1), so modify
all window management routines to support 2 windows of DECON-INT
and 1 window of DECON-EXT.
