arm64: dts: rockchip: Add frl-enable-gpios to rk3576-nanopi-r76s
The board exposes the GPIO4_C6 pin to control the voltage bias on the
HDMI data lines. It must be asserted when operating in HDMI 2.1 FRL
mode and deasserted for HDMI 1.4/2.0 TMDS mode.
Wire up the hdmi node to its dedicated GPIO via frl-enable-gpios to
allow adjusting the bias when transitioning between TMDS and FRL modes.
Additionally, drop the now unnecessary workaround of using vcc5v_hdmi_tx
as hdmi-pwr-supply solely to drive the GPIO into its default state.
