MISRA-C requires that the controlling expression of an if statement or
an iteration-statement shall be Boolean type.
v1 -> v2:
* update the U suffix of constant to let the type of operands
to bit operations (&) is the same.
* update the type of 'i' from uint64_t to uint16_t in
'profiling_set_control' since it is limited by phys_cpu_num,
which is uint16_t.

When a macro is expanded, the two tokens on either side of each ‘##’ operator
are combined into a single token, which then replaces the ‘##’ and the two
original tokens in the macro expansion. So we need use CAT__ to expand the
__LINE__ MACRO and use CAT_ to combine the expaneded MACRO.

- Fix the integer violations related to the following rules:
1. The operands to shift operations (<<, >>) shall be unsigned
integers.
2. The operands to bit operations (&, |, ~) shall be unsigned
integers.
- Replace 12U with CPU_PAGE_SHIFT when it is address shift case.
v1 -> v2:
* use existed MACRO to get bus/slot/func values
* update PCI_SLOT MACRO to make it more straightforward
* remove the incorrect replacement of 12U with CPU_PAGE_SHIFT

Currently vpci treats IO port CF9 as a regular PCI CONFIG_ADDRESS port,
so that SOS can't do system reboot through port CF9.
This patch handles port CF9 in this way:
- SOS (vm0): it is allowed to actually access the physical IO port for byte
accesses.
- UOS (non-vm0) or partitioning guests: any accesses to port CF9 are
ignored.

MMIO registers might be changed at any time.
The changes might not be catched due to compiler optimization
if there is no 'volatile' keyword.
We have defined MMIO read/write APIs to address the above issue.
'volatile' keyword is being used in these defined MMIO read/write
APIs.
This patch updates the MMIO registers access implementation in
'msix.c' to use these defined MMIO read/write APIs.

- new way:
