The support for a spd.bin from CBFS was removed for all mc_ehl boards in
commit 833bb448c5 (mb/siemens/mc_ehl: Remove spd.bin from CBFS).
There is still a remaining comment in romstage_fsp_params.c referring to
the removed capability. This fix removes the spd.bin related part of the
comment to stay consistent with the code.

VGA defined the extended ASCII set based on CP437, but the function
vga_write_text() accepts a signed char array.
This will cause unnecessary confusion that if we want to print u with
umlaut (code=129 in CP437), we need to explicitly cast it to -127 in
signed char.
Since we still want to leverage the built-in string utilities
which only accepts const char*, we still need to cast it to signed char
while processing, and cast it back to unsigned once we write into the
frame buffer.

walkcbfs_asm is a simple CBFS implementation in assembly to find a file
on a system with memory-mapped SPI flash. It seems to be mostly unused
nowadays and is only still called for early microcode loading on some
old systems (e.g. FSP 1.1 and older).
Using this implementation with CONFIG_CBFS_VERIFICATION is unsafe
because it does not verify the hashes the way the normal CBFS code does.
Therefore, to avoid potential security vulnerabilities from creeping in,
this patch makes sure the code cannot be compiled in when
CBFS_VERIFICATION is active. That means it won't be supported on the old
boards using this for microcode loading.
Ideally CONFIG_CBFS_VERIFICATION should have a `depends on` to make this
dependency more obvious in menuconfig, but the configs actually using
this code are not easy to untangle (e.g. CONFIG_MICROCODE_UPDATE_PRE_RAM
is just set everywhere by default although only very few boards are
really using it, and a lot of different old Intel CPU models are linking
in src/cpu/intel/car/non-evict/cache_as_ram.S without being united under
a single Kconfig so that's not easy to change). To keep things simple,
this patch will just prevent the code from being built and result in a
linker error if a bad combination of Kconfigs is used together. Later
patches can clean up the Kconfigs to better wrap that dependency if the
affected boards are still of enough interest to be worth that effort.
