arm64: dts: mt7986: add Bananapi R3
Add support for Bananapi R3 SBC.
- SD/eMMC support (switching first 4 bits of data-bus with sw6/D)
- SPI-NAND/NOR support (switched CS by sw5/C)
- all rj45 ports and both SFP working (eth1/lan4)
- all USB-Ports + SIM-Slot tested
- i2c and all uarts tested
- wifi tested (with eeprom calibration data)
The device can boot from all 4 storage options. Both, SPI and MMC, can
be switched using hardware switches on the board, see
