configurations/ampere: organize configs

Organizing configs by hardware vendor has some advantages:
- quickly find configs for hardware
- easily review config changes for hardware you are using via gerrit
path matches
- harder to overlook toplevel files like `VENDORS.md` and `meson.build`
- more easily see which config is relevant for some hardware

Organizing config like this has precedent in linux [1].
