v1-v2:
Bypass this case:
When binary arithmetic operators of different precedence (e.g. '+'
and '*') are mixed in an expression, parentheses are added to the
sub-expressions using the operator with a higher precedence.
v1:
The operator precedence rules are complicated and it is easy to make a mistake.
So add brackets to make operator expression more readable.

The npk_log is a log destination for the hypervisor, similar to the
console_log and the mem_log. It can be enabled/disabled/configured
by the SOS kernel via the hypercall HC_SETUP_HV_NPK_LOG.
The configuration includes:
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
the MMIO address of the reserved NPK master with a simple header.

MISRA-C requires that shift operation cannot exceed the word length.
What this patch does:
- Fix the bug in 'vuart_init'
The register 'dll' and 'dlh' should be uint8_t rather than char.
'dll' is the lower 8-bit of divisor.
'dlh' is the higher 8-bit of divisor.
So, the shift value should be 8U rather than 16U.
- Fix other data type issues regarding to the registers in 'struct
vuart'
The registers should be unsigned variables.
v1 -> v2:
* Use a local variable 'uint8_t value_u8 = (uint8_t)value' to avoid
mutiple times type conversion
* Use '(uint8_t)divisor' rather than '(uint8_t)(divisor & 0xFFU)' to
get the lower 8 bit of 'divisor'
Direct type conversion is safe and simple per Xiangyang's suggestion.

In the hypervisor, physical cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about physical cpu id (pcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.
In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is
broadcast pcpu_id used to notify all valid pcpu.
The type of pcpu_id in the struct vcpu and vcpu_id is "int" type,
this will be fixed in another patch.
V1-->V2:
* Change the type of pcpu_id from uint32_t to uint16_t;
* Define INVALID_PCPU_ID for error detection;
* Define BROADCAST_PCPU_ID to notify all valid pcpu.
V2-->V3:
* Update comments for INVALID_PCPU_ID and BROADCAST_PCPU_ID;
* Update addtional pcpu_id;
* Convert hexadecimals to unsigned to meet the type of pcpu_id;
* Clean up for MIN_PCPU_ID and MAX_PCPU_ID, they will be
