I guess we would like to call it something like "cros_ec_get_cmd_versions".

Could it support a "version" parameter as existing EC_CMD_GET_CMD_VERSIONS
usages use both versions? An `u16 cmd` parameter and down-cast to u8 for v0
should be fine. (ec_params_get_cmd_versions vs. ec_params_get_cmd_versions_v1)
