arm64: dts: rockchip: fix HDMI-RX signal detect GPIO on yy3588

Browse Source 
The YY3588 declares the HDMI-RX signal detect on GPIO1_C6, but the
receiver never sees an attached source there and cannot capture any
input.

That value was copied from the vendor device tree and is wrong. The
core-board schematics are not available and the SoM documentation does
not clearly show where this signal is routed, so the correct pin was
read from the device tree in the board's Android image: GPIO1_D5. With
GPIO1_D5 the receiver detects a connected source and locks, and v4l2
reports the input timing (1920x1080p60).
