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.
