Donghwa Lee 7258cc14f3 video: support MIPI-DSI controller driver 
Samsung S5PC210 and EXYNOS SoC platform has MIPI-DSI controller and
MIPI-DSI based LCD Panel could be used with it.  This patch supports
MIPI-DSI driver based Samsung SoC chip.

LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at
machine code and LCD panel driver specific function registered to
mipi_dsim_ddi structure at lcd panel init function called system init.  In
the MIPI-DSI driver, find lcd panel driver by using registered lcd panel
name, and then initialize lcd panel driver.
