ARM: dts: r8a7779, marzen: Fix DU clock names
[ Upstream commit 6ab8c23096a29b69044209a5925758a6f88bd450 ]
"make dtbs_check" complains:
arch/arm/boot/dts/r8a7779-marzen.dt.yaml: display@fff80000: clock-names:0: 'du.0' was expected
Change the first clock name to match the DT bindings.
This has no effect on actual operation, as the Display Unit driver in
Linux does not use the first clock name on R-Car H1, but just grabs the
first clock.
