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.

In the C99 standard, the order of evaluation associated with
multiple #, multiple ## or a mix of # and ## preprocessor
operator is unspecified. For this case, gcc 7.3.0 manual
does not specify related implementation. So it is unsafe
to use multiple # or ## in a macro.
BTW, there are some macros with one or more "##" which are
not used by hypervisor.
Update relate codes to avoid using multiple # or ## in a macro;
Remove unused macros with one or more "##";
Remove "struct __hack;" at the end of GETCC since it is useless.
Note:
'##' operator usage constraints: A ## preprocessing token shall
not occur at the beginning or at the end of a replacement list
for either form of macro definition.
V1--V2:
Update relate codes to avoid using multiple # or ## in a macro.
V2-->V3:
Remove unused macros with one or more "##";
Remove "struct __hack;" at the end of GETCC since it is useless.

In the current memory module, there are many constatn value
without U/UL suffix, it is reported as MISRA C violations by
static analysis tool.
Add 'U/UL' suffix for unsigned contant value in memory module
as needed.
Note:In the most case, CPU_PAGE_SIZE(0x1000) is used as
unsigned integer contant value, so CPU_PAGE_SIZE is defined
as unsigned integer contant value, and it is safety converted
into unsigned long type according to MISRA C standard.
