drm: initialize default rotation value to DRM_ROTATE_0 

When no console framebuffer is enabled, the default plane state is
defined by plane reset function. If driver uses generic helper, then
rotation property is set to zero. This is not a valid value for that
enum. This patch sets default rotation value to DRM_ROTATE_0.
