Subject: [PATCH v4 15/19] fpga: dfl: convert is_feature_dev_detected() to use FIU type

Use binfo->type instead of binfo->feature_dev to decide whether a
feature device was detected during feature parsing. A subsequent
commit will delay the allocation of the feature platform device
to feature_dev_register() and remove binfo->feature_dev.

This commit does not introduce any functional changes.
