arm64: dts: rockchip: Fix LED triggers on rk3308-roc-cc

[ Upstream commit 3a53a7187f41ec3db12cf4c2cb0db4ba87c2f3a1 ]

There are two LEDs on the board, power and user events.
Currently both are assigned undocumented IR(-remote)
triggers that are probably only part of the vendor-kernel.

To make dtbs check happier, assign the power-led to a generic
default-on trigger and the user led to the documented rc-feedback
trigger that should mostly match its current usage.
