Subject: [PATCH v1 1/2] arm64: dts: ti: k3-am69-aquila-dev: Fix USB-C Sink PDO

From: Francesco Dolcini <francesco.dolcini@...adex.com>

Change USB-C Sink PDO and the amount of power that the device can sink
to zero to maximize compatibility with other USB peers (the Aquila
Development Board is not sinking any current, it is self powered).

Fixes: 39ac6623b1d8 ("arm64: dts: ti: Add Aquila AM69 Support")
