hv: PTM: Add virtual root port Add virtual root port that supports the most basic pci-e bridge and root port operations. - init_vroot_port(): init vroot_port's basic registers. - deinit_vroot_port(): reset vroot_port - read_vroot_port_cfg(): read from vroot_port's virtual config space. - write_vroot_port_cfg(): write to vroot_port's virtual config space.

hv: PTM: Create virtual root port Create virtual root port through add_vdev hypercall. add_vdev identifies the virtual device to add by its vendor id and device id, then call the corresponding function to create virtual device. -create_vrp(): Find the right virtual root port to create by its secondary bus number, then initialize the virtual root port. And finally initialize PTM related configurations. -destroy_vrp(): nothing to destroy Tracked-On: #5915 Signed-off-by: Rong Liu <rong.l.liu@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com> Acked-by: Jason Chen <jason.cj.chen@intel.com> Acked-by: Yu Wang <yu1.wang@intel.com>
