arm64: dts: rockchip: Add base DT for rk3588 SoC
This initial version supports CPU, dma, interrupts, timers, UART and
SDHCI (everything necessary to boot Linux on this system on chip) as
well as Ethernet, I2C, PWM and SPI.
The DT is split into rk3588 and rk3588s, which is a reduced version
(i.e. with less peripherals) of the former.
