drm/exynos: Implement mmap as GEM object function
Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.
The respective exynos functions are being removed. The file_operations
structure exynos_drm_driver_fops is now being created by the helper macro
DEFINE_DRM_GEM_FOPS().
