From: Tom Rix <[email protected]>
Follow drivers/net/ethernet/ which has control configs
NET_VENDOR_BLA that map to drivers/net/ethernet/bla
Since fpgas do not have many vendors, drop the 'VENDOR' and use
FPGA_BLA.
There are several new subdirs
altera/
dfl/
lattice/
xilinx/
Each subdir has a Kconfig that has a new/reused
if FPGA_BLA
... existing configs ...
endif FPGA_BLA
Which is sourced into the main fpga/Kconfig
Each subdir has a Makefile whose transversal is controlled in the
fpga/Makefile by
obj-$(CONFIG_FPGA_BLA) += bla/
This is the dfl/ subdir part.
Create a dfl/ subdir
Move dfl-* files to it.
Add a Kconfig and Makefile
Because FPGA_DFL is now used in dfl/Kconfig in a if/endif
block, all the other configs in dfl/Kconfig implicitly depend
on FPGA_DFL. So the explicit dependence can be removed. Also
since FPGA_DFL depends on HAS_IOMEM, it can be removed from the
other configs.

You should update Documentation/fpga/dfl.rst too as it mentions
"drivers/fpga/dfl-fme-pr.c". This update was in your initial patch 5 so
it's lost now, but it really should be in this patch.
