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.

Fixes: eb4d9796fa34 ("drm/exynos: g2d: Convert to driver component API")
