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-
es accessible in files.

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.

According to the comments in hypervisor:
" This file includes config header file "bsp_cfg.h" and other
hypervisor used header files.
It should be included in all the source files."
this patch includes all common header files in hypervisor.h
then removes other redundant inclusions

Add percpu earlylog sbuf within hypervisor memory space to accommodate log
before sos booting, and copy the earlylog to SOS allocated sbuf at the first
do_logmsg after SOS sets the sbuf during booting.
With the patch, earlylog of hypervisor could be captured with acrnlog
service if SOS booted. And it may help debugging hv issue if SOS failed to
boot, with "logdump" command.
