    drm/exynos: fix g2d_open/close helper function definitions
    
    [ Upstream commit 2ef0785b30bd6549ddbc124979f1b6596e065ae2 ]
    
    The empty stub functions are defined as global functions, which
    causes a warning because of missing prototypes:
    
    drivers/gpu/drm/exynos/exynos_drm_g2d.h:37:5: error: no previous prototype for 'g2d_open'
    drivers/gpu/drm/exynos/exynos_drm_g2d.h:42:5: error: no previous prototype for 'g2d_close'
    
    Mark them as 'static inline' to avoid the warning and to make
    them behave as intended.
