stable inclusion from stable-v6.6.7 commit 2e594ee138c91ded4223e7c705920108d511877b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8SSQ4

--------------------------------
[ Upstream commit dc761f11af2e39119d3a7942e3d10615f3d900e7 ]
The LED ACT which is included from bcm2711-rpi-4-b doesn't exists on the Raspberry Pi 400. So the bcm2711-rpi-400.dts tries to use the delete-node directive in order to remove the complete node. Unfortunately the usage get broken in commit 1156e3a78bcc ("ARM: dts: bcm283x: Move ACT LED into separate dtsi") and now ACT and PWR LED using the same GPIO and this prevent probing of led-gpios on Raspberry Pi 400:
leds-gpio: probe of leds failed with error -16
So fix the delete-node directive.
