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.

MISRA-C requires that each function defined and declared shall be called
or referenced in code analyzed.
In some cases, we would like to keep the non-called functions for code
completeness, such as
vcpu_inject_extint/vcpu_inject_nmi/vcpu_inject_gp/vcpu_inject_pf
/vcpu_inject_ud/vcpu_inject_ac/vcpu_inject_ss.
This pacth removes some functions that are independent and are not

MISRA-C requires that each parameter in the MACRO shall be in brackets.
In some cases, adding brackets for all of the parameters may not be a
perfect solution.
For example, it may affect the code readability when there are many
parameters used in the MACRO.
And duplicated brackets will appear when one MACRO called another MACRO
which is using same parameters.
This patch convert some MACROs to inline functions to avoid such cases.

1. Set the MMIO base address of the reserved NPK master.
2. Set the log level of the hypervisor NPK log.
After that, the npk_log can be enabled to write the hypervisor logs to
