serial PCI device is just used for HV/SOS output debug information;
because it is used in hypervisor layer, SOS should not touch it.
so need to check and hide it from SOS.

This patch allows to disable the serial port directly from Kconfig. This used
to only be possible from the command-line (by passing "uart=disabled"). To
disable the serial port via Kconfig, simply unselect the "Serial IO type"
option.
The default options do not seem to have any effect anymore (and were confusing
anyway) so they are removed and the serial port is enabled for various platforms
in their corresponding *.config file.

The printf related functions have been called by other various

MISRAC has requirement about implict conversion: actual to formal
param. This patch is used to fix part of these violations.
1.Add a new structure seg_desc_vmcs to hold the VMCS field address of
segment selector to clean up seg_desc structure.
2.Add the definition of maximum MSI entry and the relevant judgement.
3.The violations in shell.c, logmsg.c will be fixed in other series of
patches with modification of function snprintf(), vsnprintf() and other
related usages.
v1->v2:
*Move the definition of struct seg_desc_vmcs from instr_emul.h to
instr_emul.c.
*Modify the formal parameter type in function definition from uint8_t
to char instead of using cast.
*Drop the const declaration for char data in formal parameter.
v2->v3:
*update the data missing conversion.
*change type of internal parameter len to avoid casting in npklog.c.
*change the conversion from signed char to unsigned int in
uart16550_getc() to solve sign-extension.

There are many type conversions in the atomic
operations invoking reported by static analysis tool. These
type conversions voilate MISRA C.
To keep uniform naming convention, rename atomic operation
function names:
atomic_set_int/long --> atomic_set32/64;
atomic_clear_int/long --> atomic_clear32/64;
atomic_load --> atomic_load32;
atomic_store --> atomic_store32;
atomic_swap --> atomic_swap32;
atomic_readandclear --> atomic_readandclear32;
atomic_inc --> atomic_inc32;
atomic_dec --> atomic_dec32;
atomic_cmpxchg --> atomic_cmpxchg32;
atomic_xadd --> atomic_xadd32.
Update the type of atomic_load32/64, atomic_store32/64,
atomic_swap32/64, atomic_cmpxchg32/6.
Update related variables and callers.
Note: the type of return value and parameters of atomic_xadd32/64
still keep signed int/long since caller pass
negative variable to atomic_xadd32/64;
V1-->V2:
Add comments for atomic_set/clear to differ from
bitmap_set/clear.

1) Change these 5 APIs to void type:
vcpu_inject_pf
uart16550_calc_baud_div
uart16550_set_baud_rate
console_init
ptdev_activate_entry
No need to return 'entry' for ptdev_activate_entry
since the input parameter is 'entry'.
2) no need to check return value for the caller
such as sbuf_put/console_putc/serial_puts/serial_get_rx_data

To prevent the value is devided by zero, checks the denominator
before the calculation. Adding the if statement to check before use.
If the baud_rate is equal to zero, using default baud_rate.
