mcb: Add missing modpost build support 



mcb bus is not prepared to autoload client drivers with the data defined on
the drivers' MODULE_DEVICE_TABLE. modpost cannot access to mcb_table_id
inside MODULE_DEVICE_TABLE so the data declared inside is ignored.

Add modpost build support for accessing to the mcb_table_id coded on device
drivers' MODULE_DEVICE_TABLE.
