drm/exynos: fix build warnings

The commit fe6367c905b6 ("drm/exynos/mixer: enable HDMI-PHY before
configuring MIXER") causes many build warnings like below:

In file included from drivers/gpu/drm/exynos/exynos_drm_drv.c:23:0:
drivers/gpu/drm/exynos/exynos_drm_drv.h:320:13: warning: 'exynos_hdmiphy_enable' defined but not used [-Wunused-function]
 static void exynos_hdmiphy_enable(struct exynos_drm_crtc *crtc) {}
             ^
...

Make to inline function exynos_hdmiphy_enable to avoid build warnings.
