arm64: dts: rockchip: Update leds for Odroid Go Advance
Update the blue LED to be controlled via pwm to enable control of LED
brightness. Add red LED as a GPIO controlled LED. The documentation
stated "label" was depreciated so function and color was used instead.
The LED names (led-2 and led-3) are given because that is what they
are numbered on the board itself; LED 1 is wired directly into an
always on regulator and is not controllable. LED 2 is labelled "alive"
on the board and documentation recommends we set the function as
status over other miscellaneous functions. LED 3 is labelled "chg" on
the board.
