Subject: [PATCH 2/3] arm64: dts: rockchip: Add RK3399 Rock Pi 4a plus board

Rock Pi 4a plus board is the successor of Rock Pi 4a board.

Differences to the original version are
- has RK3399 OP1 SoC revision
- has eMMC (16 or 32 GB) soldered on board (no changes required,
  since it is enabled in rk3399-rock-pi-4.dtsi)
- dev boards have SPI flash soldered, but as per manufacturer response,
  this won't be the case for mass production boards

I didn't add yet another compatible, since the small set of differences
are captured by the device tree.
