[PATCH] arm: dts: renesas: r8a77980: Remove r8a77970 DU compatible

[Kieran Bingham]

The r8a77970 was added with an compatible string for a differnet device
rather than adding the correct compatible to the driver.

Remove the unnecessary compatible which is for a different platform.

Please note, this patch should not be integrated until the renesas,du-r8a77980
compatible string makes it into the DU [0].
