For Verilator >5.019 `-Wno-GENUNNAMED` needs to be added to LINT_FLAGS
to silence warnings from the cell library.

- NOTE: This is an optional feature, not built by default. Not included
in the tk1 for sale at Tillitis shop.
- This makes it possible to interface the SPI flash onboard TKey.
- To include the SPI master in the build, use `make application_fpga.bin
YOSYS_FLAG=-DINCLUDE_SPI_MASTER`.

- Exclude splint from CI, so we make another target for it "splint",
which we might include in the "check" target later.
- Move the analysis runs earlier in CI so they, including indentation
checks, fail first.
- Include printouts of hashen in check-binary-hashes to easier see
what the digest are if it fails in CI.
By patching the UDS and UDI into an already built bitstream, it is now
not necessary to rebuild the entire build flow when changing the UDS
and the UDI. This lowers re-build times significantly.

The testbenches live in their own Makefiles under
hw/application_fpga/core/*/toolruns (except picorv32). Let's add a
top-level target to build and run them.
In order to run core testbenches, use
cd hw/application_fpga
make tb
or if using Podman:
cd contrib
make run-tb
to run the same target in a container.
Add clang-tidy and splint static analytics check. For now, we use only
the cert-* warnings on clang-tidy and run splint with a lot of flags
to allow more things.
Changes to silence these analytics:
- Stop returning stuff from our debug print functions. We don't check
them anyway and we don't have any way of detecting transmission
failure.
- Declare more things static that isn't used outside of a file.
- Change types to be more consistent, typically to size_t or
something or to uint32_t.
Introduce memcpy_s() and wordcpy_s() that takes the destination buffer
size as an argument. Use assert() which aborts our program to an
eternal loop if we hit problems.
Sprinkle asserts elsewhere as well.

In firmware we store the address to firmware blake2s() function at
TK1_MMIO_TK1_BLAKE2S so app can use this firmware function sort of
like a system call but without context switch.
Silence lint on intentional combinatinal loops
Use better instance names, and a single lint pragma for all macros
Remove unused pointer update signals
Silence lint on wires where not all bits are used
Change fw_app_mode to be an input port to allow access control
