Subject: [PATCH v2] arm64: dts: rockchip: move uart2 pinmux to dtsi on rk3588-tiger

From: Heiko Stuebner <heiko.stuebner@...rry.de>

The association of uart2 to the q7-uart pins is part of the module
itself and not the baseboard used. Therefore move the pinctrl over
to the tiger dtsi.

- add comment specifying where the signals go to on the Q7 connector
- add Quentin's review
