Subject: [PATCH v2 1/2] video: fbdev: exynos: Remove old non-working MIPI driver
The old non-DRM Exynos MIPI driver does not support DeviceTree and
requires board files. Our platforms do not provide such so the driver
is not usable since a long time ago. All features provided by the
driver (and associated s6e8ax0 panel driver) are already supported by
newer DRM version so the old code can be removed.
