pin gpio3 already requested by leds

[strangerting]

this seems similar to #2856

any ideas as to why this is happening on a pi4? shutdown doesnt happen gracefully:-

[ 7.868329] pinctrl-bcm2835 fe200000.gpio: pin gpio3 already requested by leds; cannot claim for soc:shutdown_button
[ 7.868354] pinctrl-bcm2835 fe200000.gpio: pin-3 (soc:shutdown_button) status -22
[ 7.868375] pinctrl-bcm2835 fe200000.gpio: could not request pin 3 (gpio3) from group gpio3 on device pinctrl-bcm2711
[ 7.868397] gpio-keys soc:shutdown_button: Error applying setting, reverse things back
[ 7.868435] gpio-keys: probe of soc:shutdown_button failed with error -22

I've noticed that there are a lot of issues on shutdown when the firmware for the Pi isn't up to date.
