[PATCH v3 07/23] drm: atmel: use vblank hooks in struct drm_crtc_funcs

[Shawn Guo]

From: Shawn Guo <shawn.guo at linaro.org>

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers.  For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
