[PATCH 0/9] MISRA C 2012 8.1 rule fixes

[Michal Orzel <michal.orzel@xxxxxxx>]

This series fixes all the findings for MISRA C 2012 8.1 rule, reported by
cppcheck 2.7 with misra addon, for Arm (arm32/arm64 - target allyesconfig).
Fixing this rule comes down to replacing implicit 'unsigned' with explicit
'unsigned int' type as there are no other violations being part of that rule
in the Xen codebase.

The last three patches contain fixes for files that originated from other
projects like Linux kernel or libfdt, therefore they are rather not applicable
to be fixed in Xen (they can be dropped). Nevertheless they act as a sign to
what should be added to a deviation list.

Some important notes:
Static analyzers are not perfect. Cppcheck generates internal AST error for some
of the files resulting in skipping all the checks. For these files, one need to
manually check if there are no findings.

Recently there was a release of a new Cppcheck 2.8 version. However it contains
a regression bug with misra addon. Therefore do not use that version for now.
