At present this function sits in its own file but it does not really
justify it. There are similar string functions in vsprintf.h, so move it
there. Also add the missing function comment.

Use the vsprintf.h include file explicitly where needed.

"i" gets incremented before we're entering loop body
and effectively we iterate from 1 to 8 instead of 0 to 7.

This way we:
 a) Skip the first line of struct hs_versions
 b) Go over it and access memory beyond the structure

1. Try to guess a ARC core template that was used
   i.e. not just name a core family but something more
   menaingful like "ARC HS38", "ARC EM11D" etc.

   We do it checking availability of the key differentiation
   features like:
    - Caches (we actually only check for L1 I$ fpr simplicity)
    - XY-memory
    - DSP extensions etc.

2. Identify ARC subsystems

3. Print core clock frequency

This allows board to override print_cpuinfo() because
they might know better which ARChitect template was used.
This way we may not only derive base architecture type and
version but more meaningful things like "ARC EM7D" instead of
simple "ARC EM", "ARC HS36" instead of "ARC HS".

Once we enable DISPLAY_CPUINFO for ARC we'll see
ARC core family and version printed on boot.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

ISS is obsolete now and nSIM is used for simulation instead.
In its turn nSIM properly handles baud-rate settings so get rid
of now useless check.
