Subject: [PATCH 1/3] arm64: dts: rockchip: enable internal pull-up on
 Q7_USB_ID for RK3399 Puma

From: Quentin Schulz <quentin.schulz@...obroma-systems.com>

The Q7_USB_ID has a diode used as a level-shifter, and is used as an
input pin. The SoC default for this pin is a pull-up, which is correct
but the pinconf in the introducing commit missed that, so let's fix this
oversight.
