Need for ways to express different config_registers definition for variants

[elfmimi]

for example, config_registers definition in 0x11-CH55x.yaml is currently correct only for CH559.

Yes. This needs to be fixed.

A hack I use is https://github.com/ch32-rs/wchisp/blob/main/devices/0x12-CH54x.yaml

https://github.com/ch32-rs/wchisp/blob/aedf69aa685f57db1d623d828920f06277471505/devices/0x12-CH54x.yaml#L10

Close this. To see how to express different config_registers definitions for variants: https://github.com/ch32-rs/wchisp/blob/main/devices/0x13-CH57x.yaml
