i2c: mux: mlxcpld: Get rid of adapter numbers enforcement
Do not set the argument 'force_nr' of i2c_mux_add_adapter() routine, instead provide argument 'chan_id'. Rename mux ids array from 'adap_ids' to 'chan_ids'. The motivation is to prepare infrastructure to be able to: - Create only the child adapters which are actually needed - for which channel ids are specified. - To assign 'nrs' to these child adapters dynamically, with no 'nr' enforcement.
