If OF_CONTROL is not enabled and DM_SEQ_ALIAS is enabled, we must assign an alias (requested sequence number) to devices that belongs to a class with the DM_UC_FLAG_SEQ_ALIAS flag. Otherwise uclass_find_device_by_seq() cannot be used to get/probe a device. In particular i2c_get_chip_for_busnum() cannot be used.

Changes in v2:
- don't use the DT to find the req_seq number if SPL_OF_PLATDATA is used. Instead do it as if SPL_OF_CONTROL is not defined.

Using sequence numbers without OF_CONTROL is a tricky case. This looks OK though.
