drm/ast: Upcast from DRM device to ast structure via to_ast_private()

Browse Source 
All upcasting from struct drm_device to struct ast_private is now
performed via to_ast_private(). Using struct drm_device.dev_private
is deprecated. The ast variable in ast_crtc_helper_atomic_check() is
unused, so removed it.

v2:
	* fix typo in commit message
