PCI: hv: Introduce hv_msi_entry
Add a new structure (hv_msi_entry), which is also defined in the TLFS,
to describe the msi entry for HVCALL_RETARGET_INTERRUPT. The structure
is needed because its layout may be different from architecture to
architecture.
Also add a new generic interface hv_set_msi_entry_from_desc() to allow
different archs to set the msi entry from msi_desc.
No functional change, only preparation for the future support of virtual
PCI on non-x86 architectures.
