WIP: add initial support for Youyeetoo R1 V3 (#7108)

* youyeetoo r1 v3: add initial support for this board

* arch: arm64 board: youyeetoo r1 v3 replace edge with vendor kernel

* arch: arm64 board: youyeetoo r1 v3 reviews changes:
- Removed patch, see the pr for more details #7108
- Removed old kernel legacy
- WIP: Added DTS code on armbian/linux-rockchip#223

I compiled the OS with latest changes, untested build logs in https://paste.armbian.com/ofidozaqup

* Update: Rename board from V3 to v3 (ARM64, Youyeetoo R1)
- Note: Untested on v1 as I don't have a v1 board available.
