366042cac2 hv: fix integer violations
- Fix the integer violations related to the following rules:
  1. The operands to shift operations (<<, >>) shall be unsigned
     integers.
  2. The operands to bit operations (&, |, ~) shall be unsigned
     integers.

- Replace 12U with CPU_PAGE_SHIFT when it is address shift case.

v1 -> v2:
 * use existed MACRO to get bus/slot/func values
 * update PCI_SLOT MACRO to make it more straightforward
 * remove the incorrect replacement of 12U with CPU_PAGE_SHIFT
   dmar_fault_msi_write

dcebdb8e98 hv: implement msi.c to handle MSI remapping for vm0
Emulate MSI Capability structure for vm0 in sharing mode:

- it intercepts the IO requests for MSI Capability structure, emulates
  the Message Control word, and bypasses all other I/O requests to the
  physical device.

- criteria to trigger MSI remapping: MSI Enable bit is being changed,
  Message Data/Addr is being changed when MSI Enable is set.

ec5b90f11e hv: implement PCI bus scan function
- It starts from scaning bus 0 and scan other buses only if it is referred
  as a Secondary Bus by a PCI-to-PCI bridge.
- Skip to next device if function 0 is not implemented.
- Don't enumerate function 1-7 if a device is not a multi-function device.

9cc1f57f63 hv: change function parameters: pci_pdev_read_cfg and pci_pdev_write_cfg
In order to allow these functions to be called without an associated
struct pci_pdev (for example, at the time of PCI bus enumeration), these
two functions can not take the struct vdev as input parameter.

bc4f82d1d1 hv: more cleanup for pci.h
Don't have any logical changes.
- add more common PCI macros
- remove redundant definitions in dmar_parse.c
- move all the common mascos from vpci.h to pci.h

4741fcfff2 hv: pci_priv.h code cleanup
- move most of the content of pci_priv.h to include/dm/pci.h.
  This allows other code outside dm/vpci to be able to share these macros.
- code cleanup: fix alignments etc.
