[v8,5/5] arm64: dts: mt7986: add Bananapi R3

  From: Frank Wunderlich <frank-w@public-files.de>

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
https://wiki.banana-pi.org/Banana_Pi_BPI-R3#Jumper_setting

changes:
v8:
- drop model string override in emmc-dtso
- drop cs-gpios from spi-nodes
- add interrupt-settings for mt7531 switch

v7:
- squashed overlay-patch and converted sd/emmc dts to overlay too
- moved mmc-regulators to base dts
- changed common dtsi to (base dts) and overlay extension to dtso

v6:
- drop usb 5v regulator from bpi-r3
  based on chunfengs response it is only needed if regulator is
  switched (like for otg), usb works without it.

v4:
- add PCIe nodes
- fix sfp-properties of sfp-1 (need to be plural)
  thx to Denis Odintsov for this

v3:
- rename factory-key to reset-key
- add dcin regulator and add it as input for 3v3 (with renaming)
- remove memory-node
- dropped wifi eeprom (calibration) data
- move mmc0 pinctrl to common dtsi and drop sdcard comment
- change mmc pull-up/down to have generic bias-pull*

v2:
- remove pcie to be added later (discussion about clocks)
- some fixes based on suggestions on ML
  - add key suffix like it's done in mt7622-bpi-r64 devicetree
  - add dash in sfp node names
  - use reg as unit for switch-node
  - drop "-3-4" suffix from i2c-pins node name
  - fix order in Makefile

There is another model string here which shouldn't be.
