Subject: [PATCH v3 2/3] ARM: dts: stm32: fix dtbs_check warning on ili9341 dts binding

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

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

Fixes: a726e2f000ec ("ARM: dts: stm32: enable ltdc binding with ili9341, gyro l3gd20 on stm32429-disco board")
