[PATCH 4/4] arm64: dts: meson: add support for BananaPi M2-Pro

[Christian Hewitt]

BPI-M2-PRO is based upon the BPI-M5 design except for a different
physical board layout and the following changes:

- USB 3.0 ports reduced from 4x to 2x
- 3.5mm Combined CVBS/Audio Jack removed
- RTL8821BU WiFi/BT module (internal USB connected)
