HV: decouple legacy vuart interface from acrn_vuart layer

Browse Source 
support pci-vuart type, and refine:
1.Rename init_vuart() to init_legacy_vuarts(), only init PIO type.
2.Rename deinit_vuart() to deinit_legacy_vuarts(), only deinit PIO type.
3.Move io handler code out of setup_vuart(), into init_legacy_vuarts()
4.add init_pci_vuart(), deinit_pci_vuart, for one pci vuart vdev.

and some change from requirement:
1.Increase MAX_VUART_NUM_PER_VM to 8.
