arm64: dts: rockchip: add support for Firefly ROC-RK3399-PC-PLUS

ROC-RK3399-PC-PLUS is the board inside the portable Firefly Station P1 Geek
PC. As a redesign after the ROC-RK3399-PC, it uses DC-12V as power input
and spares a USB 3 host port. It is also equipped with a USB WiFi chip and
audio codec without the mezzanine board.
