Subject: [RFC PATCH v2 1/9] fpga: dfl: alias dfl_feature_dev_data to dfl_feature_platform_data

Add temporary macros that alias dfl_feature_dev_data ("fdata") to
dfl_feature_platform_data ("pdata") and associated functions from the
"fdata" to the corresponding "pdata" variants. This is done to split a
single monolithic change into multiple, smaller patches at the request of
the maintainer. The macros will be removed in the last patch of the series.

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