Subject: [RFC PATCH v2 7/9] fpga: dfl: migrate DFL support header to dfl_feature_dev_data

This change separates out most of the symbol name changes required by this
patch series for the file: drivers/fpga/dfl.h. This is done to split a
single monolithic change into multiple, smaller patches at the request of
the maintainer.

Signed-off-by: Peter Colberg <peter.colberg@...el.com>
