Add the brackets for Macro parameter to avoid the unintentional
mistakes.
A simple example that may cause mistakes:
#define minus(x) -x
When the following call is made,
z = minus(a-b)
it becomes:
z = -a-b;
where "-a - b" is equivalent to "(-a) - b" rather than "- (a - b)", as
expected.
v2 -> v3:
* convert DMAR_WAIT_COMPLETION to inline function
* remove the macro PIC_PIN_FOREACH and implement the well-formed
for loop in each case
* replace __CPP_STRING with STRINGIFY and remove the unused CPP_STRING
v1 -> v2:
* Remove some changes to function like macro since MISRA-C requires to
use inline functions if it is possible.
These MACRO brackets violations will be fixed together when fixing
other issues related to function like macro.
