PATCH 3/3 S5PV210: Add MIPI-DSI Driver.

this patch addes MIPI-DSI Driver.

to use this driver, some structures below should be added to machine specific file.

struct dsim_config
- define clock info, data lane count and video mode info for MIPI-DSI Controller.

struct dsim_lcd_config
- define interface mode, channel ID, Pixel format and so on.

struct s5p_platform_dsim
- define callbacks for initializing D-PHY, MIPI reset and trigger releated interfaces of s3c-fb.c file.
