drm/ingenic: Fix incorrect assumption about plane->index
plane->index is NOT the index of the color plane in a YUV frame.
Actually, a YUV frame is represented by a single drm_plane, even though
it contains three Y, U, V planes.
v2-v3: No change
Cc: stable@vger.kernel.org # v5.3
Fixes: 90b86fcc47b4 ("DRM: Add KMS driver for the Ingenic JZ47xx SoCs")
