Subject: [PATCHv2 21/21] arm64: dts: rockchip: Add rk3588-evb1 board

From: Kever Yang <kever.yang@...k-chips.com>

Add board file for the RK3588 evaluation board. While the hardware
offers plenty of peripherals and connectivity this basic implementation
just handles things required to successfully boot Linux from eMMC
and connect via UART.
