arm64: dts: rockchip: Add Radxa ROCK 4SE

Add board-specific devicetree file for the RK3399T-based Radxa ROCK 4SE
board. This board offers similar peripherals in a similar form-factor to
the existing ROCK Pi 4B but uses the cost-optimised RK3399T processor
(which has different OPP table than the RK3399) and other minimal hardware
changes.
