arm64: dts: rockchip: Add frl-enable-gpios to rk3588s boards
The following RK3588s boards expose a GPIO pin to control the voltage
bias on the HDMI0 data lines:
- rk3588s-coolpi-4b
- rk3588s-indiedroid-nova
- rk3588s-nanopi-r6
- rk3588s-odroid-m2
- rk3588s-orangepi-5
- rk3588s-radxa-cm5-io
- rk3588s-rock-5a
- rk3588s-rock-5c
The pin must be asserted when operating in HDMI 2.1 FRL mode and
deasserted for HDMI 1.4/2.0 TMDS mode.
Wire up the hdmi0 node to its dedicated GPIO via frl-enable-gpios to
allow adjusting the bias when transitioning between TMDS and FRL modes.
While at it, also ensure that pinctrl-names is present and ordered
alphabetically within the hdmi nodes.
