[PATCH 5.13 205/266] drm/ingenic: Switch IPU plane to type OVERLAY

[Greg Kroah-Hartman]

From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

commit 68b433fe6937cfa3f8975d18643d5956254edd6a upstream.

It should have been an OVERLAY from the beginning. The documentation
stipulates that there should be an unique PRIMARY plane per CRTC.

Fixes: fc1acf317b01 ("drm/ingenic: Add support for the IPU")
