fpga: dfl: factor out feature device data from platform device data

Browse source

Add a structure dfl_feature_dev_data to hold the DFL enumeration
info previously held in dfl_feature_platform_data. Allocate the new
structure using device-managed memory whose lifetime is bound to the
lifetime of the physical DFL, e.g., PCIe FPGA device. In a subsequent
commit, this will allow the feature platform device to be completely
destroyed and recreated on port release and assign, respectively, while
retaining the feature data in the new dfl_feature_dev_data structure.
