Subject: [PATCH v2] fpga: dfl: remove unused member pdata from struct dfl_{afu,fme}
The member pdata was added to struct dfl_afu in commit 857a26222ff7 ("fpga:
dfl: afu: add afu sub feature support") and to struct dfl_fme in commit
29de76240e86 ("fpga: dfl: fme: add partial reconfiguration sub feature
support"). It is set in function {afu,fme}_dev_init() but never used.

v2:
- Remove unused member pdata from struct dfl_fme, too.
