Subject: [PATCH 5.16 0168/1039] ARM: dts: stm32: fix dtbs_check warning on ili9341 dts binding on stm32f429 disco

From: Dillon Min <dillon.minfei@...il.com>

[ Upstream commit b046049e59dca5e5830dc75ed16acf7657a95161 ]

Since the compatible string defined from ilitek,ili9341.yaml is
"st,sf-tc240t-9370-t", "ilitek,ili9341"

so, append "ilitek,ili9341" to avoid the below dtbs_check warning.

arch/arm/boot/dts/stm32f429-disco.dt.yaml: display@1: compatible:
['st,sf-tc240t-9370-t'] is too short
