Subject: [PATCH v2 3/4] fpga: dfl: fix the comments of type & feature_id fields

The description of feature_id in struct dfl_device is not accurate. In
DFL specification the feature_id is the 12 bits field. The description
in struct dfl_device_id is more clear so we make them aligned. We also
made the similar fix for the type field.
