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

currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.
This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.

for release version, the vuart is not be used - pin 4 then is not used
by hypervisor.
this patch adds check for vm0->vuart to distinguish it.

functions ptdev_build_physical_rte & activate_physical_ioapic
doesn't need to get parameters like phys_irq, ptdev_intx_info or vector
from caller, instead they can derive from entry.

this patch is a preparation for changing ptdev remapping entry from
virtual to physical based, it changes the ptdev_lock from per-vm to
global, as entries based on physical mode are global resource.

info->phys_pin need be used by ptdev_build_native_rte when updating entry
TODO: currently ptdev entry is virtual based, the better solution should
be physical based.
