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.

Changes since v3:
- remove useless code
