arm64: dts: rockchip: Add Pine64 PineNote board

The PineNote is a tablet from Pine64 based on the RK3566 SoC, featuring
4G/128G of storage, a 10.3" electrophoretic display (EPD) with two-color
frontlight, both EMR and capacitive digitizers, dual-band wireless,
quad-channel digital microphones, and stereo speakers.

There are two existing variants of the board. v1.1 was contained in some
early samples, and v1.2 was sold as the "PineNote Developer Edition".
