Subject: [PATCH] rock-5a: add

The Radxa ROCK 5 Model A is an SBC in roughly a RaspberryPi-ish form factor
packed with a wide range of class-leading functionality, features and
expansion options. The ROCK 5A board comes in several LPDDR4x RAM memory
options: 4GB, 8GB, 16GB, and 32GB.

It uses the Rockchip RK3588S SoC (quad A76 @ 2.2GHz + quad A55 @ 1.8GHz,
Mali G610mp4 GPU), has both 8k and 4k HDMI, Gb ethernet with PoE support,
USB2/3, M.2 E Key (NVMe or SATA), a 40-pin RaspberryPi-ish 3V3 GPIO header,
USB Type-C power, MIPI DSI/CSI, SDcard slot, optional eMMC, and more.
