arm64: dts: rockchip: Add frl-enable-gpios to rk3588s-orangepi-cm5-base
The board exposes the GPIO4_B5 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.
While at it, rename the hdmi_frl_pin pinmux to hdmi0_tx_on_h, in line
with the naming commonly used in RK3588s-bassed board schematics.
