[PATCH V4 1/2] drm/exynos: add platform_device_id table and driver data for drm fimd
The name of the exynos drm fimd device is renamed to exynos-drm-fimd
and two device ids are created for exynos4-fb and exynos5-fb.
Also, added driver data for exynos4 and exynos5 to pick the timing base address
at runtime to write data into appropriate register address.
