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.

The MMIO/PIO write APIs in io.h always take a uint32_t value but may uses it as
8, 16 or 32-bit integers. This patch converts the prototypes to align with their
functionality.
The pointer conversion and assignment are splitted to separate statements to
prevent static checkers from being confused about the underlying types.
v1 -> v2:
* Change the prototype of mmio-related functions, instead of keeping the
explicit conversions internal. The addresses are kept void* since in most
cases hva (in void*) is passed.

In the current trace.h, the entries use proper unsigned types while some
function prototypes and local variables still use plain 'int', resulting in
implicit signedness conversions.
This patch makes the following conversions:
* evid: int -> uint32_t,
* n_data & cpu: 8-bit bit-field -> uint8_t,
* local variable holding the value from strnlen_s(): int -> size_t.
Note: In the following definition:
struct trace_entry {
uint64_t tsc; /* TSC */
uint64_t id:48;
....
The type of bit-field ''id'' cannot be uint32_t since gcc complains about
bit-fields larger than the type. Thus this patch keeps it as is.

Currently IOAPIC pins are represented using various types, including uint16_t,
int, uint8_t and uint32_t. This patch converts all pins to uint8_t since the
maximum number of interrupt input pins per IOAPIC is limited to 240. The special
value IOAPIC_INVALID_PIN is defined to indicate that a valid pin cannot be
found.
This type clean up also has the following impacts.
* The values in the ''legacy_irq_to_pin'' table are piggybacked with their
trigger mode. This patch splits them as the piggyback prevents us from
using a uint8_t[] for this table, and these two information are never used
at the same time.
* The ''offset'' parameter in ioapic_read_reg32 & ioapic_write_reg32 are
promoted to uint32_t to minimize explicit type conversions and keep
aligned with the type of formal parameters of mmio_(read|write)_long.
