risc-v/starfive/starfive2/d1: all of RichNeese's Risc-V boards and families - squashed
- `risc-v`: rework RichNeese's boards, reduce families, move tweaks to boards
- `risc-v`/`starfive`: `CONFIG_MOTORCOMM_PHY=m` for the onboard Ethernet
- `risc-v`/`starfive`: use mainline kernel 6.1.y, with StarFive's rebased patches against `v6.1.5`
  - from https://github.com/starfive-tech/linux/commits/visionfive
  - contention point: `1022-soc-sifive-ccache-Add-StarFive-JH71x0-support.patch` which I merged half-assed, need review/fixes?
  - `risc-v`/`starfive`: update kernel config, sans changes
- `risc-v`/`starfive`: switch from `grub` to `extlinux`
- `risc-v`/`starfive`: new `starfive` family with their (vendor) kernel
