rockchip: add Kernel 5.10 support
Remove all upstreamed patches and add the kernel configuration for
version 5.10.
The Rock Pi 4 was split in multiple versions. Add a DTS with the old
name in order to keep compatibility while having kernel 5.4 and 5.10 in
parallel. Switch to the Rock Pi 4A DTS once Kernel 5.4 support is
removed.
Tested-on: Nanoi R2S
