[PATCH v5 12/12] arm64: dts: rockchip: add support for NanoPi M6 board

From: Joachim Eastwood <[email protected]>

The NanoPi M6 (V1) board shares most of the features of the R6 boards.

Main differences:
* M.2 M-key slot with PCIe (Also present on R6C)
* M.2 E-key slot with PCIe and USB (from hub)
* 1 additional USB 2.0 port from an on-board USB hub
* RT5616 audio CODEC
