[RFC PATCH 02/18] arm: cppcheck: misra rule 20.7 deviation on processor.h

[Luca Fancellu <luca.fancellu@xxxxxxx>]

Cppcheck has found a violation of rule 20.7 for the macro __DECL_REG,
but the macro parameters are never used as an expression, they are
used for text substitution and adding parenthesis would break the
code. Cppcheck is not taking into account the context of use of the
macro argument, so we can suppress the finding.

Eclair and coverity does not report this finding.
