Create some top level configs the map to dfl pci cards.
Autoselect the parts of fpga that are needed to run these cards
as well as the defining the other subsystem dependencies.

FPGA_DFL_PCI depends on PCI, seems we also cannot select it.
> + select IFPGA_SEC_MGR
Since there is concern we cannot select all the configs, and now we have
some "depends on"s, some "select"s. It means people should manually
find and select the "depends on"s, then the helper config could appear
and be selected to finish the rest of selection.
IMHO seems this config is not as valuable as expected ...

The FPGA_DFL_FME depends on HWMON & PERF_EVENTS, seems we cannot select
it either.
