[PATCH 3/3] arm64: dts: rockchip: Mark the Orange Pi 5/5B Type-C port self-powered

[Arun Iyengar via B4 Relay <devnull+aiyengar1990.gmail.com@kernel.org>]

From: Arun Iyengar <aiyengar1990@gmail.com>

The board is powered from its separate power-only USB-C input. The
FUSB302 port's VBUS comes from vcc5v0_sys through a load switch, so the
board never runs from this port's VBUS.

Without self-powered, tcpm keeps Rp on CC during PORT_RESET (error
recovery), because opening CC on a port-powered device would remove its
own supply. With self-powered, the port opens CC for tErrorRecovery
whenever it resets, including at boot. A partner left in a stale state
by a warm reboot then sees a real detach.
