ARM: dts: microchip: Rename LED sub nodes name

dtbs_check warnings:
leds: 'd[0-9]', 'ds[0-9]' do not match any of the regexes :
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
leds: 'red', 'green', 'blue' do not match any of regexes :
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'

Rename the led sub nodes according to devicetree specification and
leds-gpio.yaml and for aks-cdu add label property and use the old node
name as value to stay stable and avoid breaking the userspace applications
that depend on those paths.
