Subject: [PATCH] arm64: dts: rockchip: fix USB on RADXA ROCK 5T

The RADXA ROCK 5T board uses the same GPIO pin for controlling the USB
host port regulator. This control pin was mistakenly left out of the
ROCK 5T device tree.

Reported-by: FUKAUMI Naoki <naoki@...xa.com>
Closes: https://libera.catirclogs.org/linux-rockchip/2025-08-25#38609886;
