MISRA-C required the suffix(U/UL), such as:
(1) ---> (1U)
(1) ---> (1UL)
(1U << 0) ---> (1U << 0U)
This patch will add the suffix(U/UL) to come up MISRA-C into
hypervisor/include directory.

MISRA-C states that redundant macros reduce the maintainability of code.
In some cases, we would like to keep the current unused macros for code
completeness, such as cpu registers. These macros might be used later.
This patch removes some unused macros that is not critical for code
completeness.
v1 -> v2:
* Keep TRUSTY_VERSION in trusty.c.
Yadong will cook another patch which will utilize TRUSTY_VERSION.

For data structure types "union lapic_id and struct segment",
its name is identical with variable name in the same scope. This MISRA C
violation is detected by static analysis tool.
Naming convention rule:If the data structure is corresponding
to hardware resource (such as register, segment selector),
its name need resource shorten name suffix (such as _reg, _sel).
The following udpates are made:
union lapic_id-->union lapic_id_reg
struct segment-->struct segment_sel

To explicit the integer constant:

to usage case.

Update parameter name and type of send_startup_ipi since
the second parameter is used as pcpu_id;

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
defined by configuration.
Note: fix bug in the init_lapic(), the pcpu_id shall be less than 8,
this is constraint by implement in the init_lapic().
