arm64: dts: rockchip: Add frl-enable-gpios to rk3588s-gameforce-ace
The board exposes the GPIO4_B3 pin to control the voltage bias on the
HDMI0 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 hdmi0 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 ddc-en-gpios property and the
associated pinctrl-* entries from hdmi0-con, and rename the hdmi0_en
pinmux to hdmi0_tx_on_h, in line with the naming commonly used in
RK3588s-based board schematics.
