arm64: dts: rockchip: Add frl-enable-gpios to rk3576-luckfox-core3576
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, remove the now unnecessary workaround of using
vcc_5v0_hdmi as hdmi-pwr-supply solely to drive the GPIO into its
default state.
Also rename the hdmi_con_en pinctrl to hdmi_tx_on_h to match the
schematic naming.
