drm/ingenic: Fix incorrect assumption about plane->index

Browse source 
[ Upstream commit ca43f274e03f91c533643299ae4984965ce03205 ]

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
