[v5,0/4] fpga: reorganize to subdirs

Message

From: Tom Rix <[e-mail]>

The incoming xrt patchset has a toplevel subdir xrt/
The current fpga/ uses a single dir with filename prefixes to subdivide owners
For consistency, there should be only one way to organize the fpga/ dir.
Because the subdir model scales better, refactor to use it.
The discussion wrt xrt is here:
https://lore.kernel.org/linux-fpga/[e-mail]/

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/

Some cleanup to arrange thing alphabetically and make fpga/Makefile's
whitespace look more like net/'s

Changes from
v1
  Drop renaming files
  Cleanup makefiles

v2
  Expand commit messages
  Add SPDX to Kconfig
  Expand new Kconfig variable help messages

v3
  Update Documentation/fpga/dfl.rst for fpga/dfl/

v4
  Restore HAS_IOMEM depends in dfl/Kconfig
  Fix vendor names in Kconfig's
