[media] davinci_vbpe: stop MEDIA_ENT_T_V4L2_SUBDEV abuse
This driver is abusing MEDIA_ENT_T_V4L2_SUBDEV: - it uses a hack to check if the remote entity is a subdev; - it still uses the legacy entity subtype check macro, that will be removed soon. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
