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.
