There are extra type conversion in the HV since cpu_id
type is uint32_t and the return value type of get_cpu_id
is uint16_t. BTW, the name of cpu_id is not clear enough
to express its usage.
So the following updates are made in this patch:
Update cpu_id type as unit_16 to reduce type casting;
Update related temporary variables type;
Update related print argument;
Change the input parameter name of interrupt_init as
cpu_id to keep align with function implement;
Rename cpu_id as pcpu_id as needed.

In the hypervisor, virtual cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about virtual cpu id (vcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.
BTW, virtual cpu id has different names (vcpu_id, cpu_id, logical_id)
for different modules of HV, its type is defined as "int" or "uint32_t"
in the HV. cpu_id type and logical_id type clean up will be done in
other patchs.
V1-->V2:
More clean up the type of vcpu id;

This patch represents TSC freqeuency in KHz using a 32-bit unsigned integer.
The conversion macros between ticks and us/ms are changed to inline functions to
enforce the types of the input parameters. Note that us_to_ticks accepts only
uint32_t (~4K us at most) and never overflows.
Results of some unit tests on the conversion functions:
calibrate_tsc, tsc_khz=1881600
64us -> ticks: 120422
64us -> ticks -> us: 63
511us -> ticks: 961497

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().

The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.
This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-

We have two sbuf for hvlog: one is allocated by hv for "early hvlog" and
the other one is allocated by SOS. Once SOS allocate the later one, the
hv allocated sbufs would be released after the contents being copied, we
call it sbuf switch.
And there is a trick here to guarantee that the switch of a certain per_cpu
sbuf is being done on exactly the certain physical CPU, that is doing the
switch at the first print after SOS allocated and setup its sbuf.
Because there are few logmsg within our current code, so will wait a bit long
for the next print. For ordinary case, it should be ok. However, for the
BTM(Boot Time Measurement) case, we need the content of "early hvlog" for
boot time calculation and it is not ok. So, we print those prints to force
the sbuf switch.
