Simone Ballarin 3e5672d69f automation/eclair: tag function calls to address violations of MISRA C:2012 Rule 13.1
Rule 13.1: Initializer lists shall not contain persistent side effects

Invocations of functions in initializer lists cause violations of rule
13.1 if the called functions are not tagged with __attribute_pure__ or
__attribute_const__ as they can produce persistent side effects.

Handling these violations with  attributes is not always possible: the
pure and const attributes may cause unwanted and potentially dangerous
optimisations.

To avoid this problem ECLAIR allows using the same attributes in the
-call_properties setting. Additionally, it adds the noeffect attribute
with the following definition:
"like pure but can also read volatile variable not triggering side effects"

These patch tags some functions used in initializer lists to address
violations of Rule 13.1.

No functional changes.
