Commited chipscope files were anyway for the 150T FPGA (AFPGA), not for the small SFPGA

It is not possible to run this anymore, among other things it depends on hdl/sim/flash/M25P128.v,
which in turns depends on a missing file (include/DevParam.h).

If we really need it we can try to restore it and revive it one day, but the SFPGA bootloader has
been stable for years as it is.

These files, when needed are now available from dependencies in hdl/ip_cores.

(for example, ddr memory model can be found in ddr controller project).

There were also some obsolete testbenches in here.

These are obsolete

After this:
	commit 156b03ec ("software: kernel:
	svec-core-fpga: Update API 'debugfs_create_regset32'")

The pointer `svec_fpga->dbg_csr` was never initialized. And when we
check it for "IS_ERR_ORNULL", we get false failure.

Thus, put conditional directive for this API update.

Some constraints were commented-out by Tristan because the golden
did not use them and Xilinx ISE was producing errors because of that.

This commits re-enables all constraints and enables an option in the Translate step of the golden
design to demote empty timegroups to warnings instead.

The xilinx-generated DDR ip-cores do not use self-refresh (the 'enter self-refresh' signal is tied
to ground). This constraint as such is not needed and many times it creates issues because ISE will
remove the signal and then Translate step will fail because it cannot match the constraint to a
signal.

1- Header-files and Module.symvers from fpga-mgr-backport project should
   only be used for the FEC-OS based on 3.10.0-957.1.3.rt56.913.el7.x86_64
   CentOS kernel.

2- Module.symvers from fmc-sw project were included twice. Thus giving
   warning for duplication.

For FPGA re-programming, debugfs was used. For this purpose, the
corresponding function was making use of 'device_schedule_callback()'
which was removed in linux-v3.15 at commit:
	33ac1257ff0dee2e9c7f009b1c1914b7990217b2 ("sysfs, driver-core:
	remove unused {sysfs|device}_schedule_callback_owner()")

The similar and better functionality is provided by an sysfs-API
'device_remove_file_self()'. Thus, convert this procedure from debugfs to
sysfs.

Variable name 'LINUX' is very ambiguous for its purpose in the makefile.
Also, this project builds as a part of COHT project which uses another
variable name 'KERNELSRC' for the same purpose. Hence, this change makes
this project uniform with others.
