To handle cpu down/up dynamically, arcn needs to support vmx off/on
dynamically. Following changes is introduced:
vmx_off will be used when down AP. It does:
- vmclear the mapped vcpu
- off vmx.
exec_vmxon_instr is updated to handle start and up AP both. It does
- if vmx was on on AP, load the vmxon_region saved. Otherwise,
allocate vmxon_region.
- if there is mapped vcpu, vmptrld mapped vcpu.

Per performance consideration, we don't flush vcpu context when doing
vcpu swithing (because it's only swithing between vcpu and idle).
But when enter S3, we need to call vmclear against all vcpus attached
to APs. We need to know which vcpu is attached with which pcpu.
This patch introduced API to get vcpu mapped to specific pcpu.

Enable VMX vpid ctrl and assign an unique vpid to each vcpu
so that VMX transitions are not required to invalidate any
linear mappings or combined mappings.
SDM Vol 3 - 28.3.3.3
If EPT is in use, the logical processor associates all mappings
it creates with the value of bits 51:12 of current EPTP.
If a VMM uses different EPTP values for different guests, it may
use the same VPID for those guests. Doing so cannot result in one
guest using translations that pertain to the other.
In our UOS, the trusty world and normal world are using different
EPTP. So we can use the same VPID for it.

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.

Pointer arithmetic is currently used to calculate the address of a specific
Local Vector Table (LVT) register (except LVT_CMCI) in lapic, since the
registers are continuously placed with fixed padding in between. However each of
these registers are declared as a single uint32_t in struct lapic, resulting
pointer arithmetic on a non-array pointer which violates MISRA C requirements.
This patch refactors struct lapic by converting the LVT registers fields (again
except LVT_CMCI) to an array named lvt. The LVT indices are reordered to reflect
the order of the LVT registers on hardware, and reused to index this lvt array.
The code before and after the changes is semantically equivalent.

It is an extension of GCC CPP to:
* allow omitting a variable macro argument entirely, and
* use ## __VA_ARGS__ to remove the the comma before ## __VA_ARGS__ when
__VA_ARGS__ is empty.
The only use of ## _VA_ARGS__ is to define the pr_xxx() macros, with the first
argument being the format string and the rest the to-be-formatted arguments. The
format string is explicitly spelled out because another macro pr_fmt() is used
to add to the format string a prefix which is customizable by defining what
pr_fmt() expands to.
For C99 compliance, this patch changes the pr_xxx() macros in the following
pattern.
- #define pr_fatal(fmt, ...) \
- do_logmsg(LOG_FATAL, pr_fmt(fmt), ## __VA_ARGS__); \
+ #define pr_fatal(...) \
+ do_logmsg(LOG_FATAL, pr_prefix __VA_ARGS__); \
