HV: add support for 64-bit bar emulation

Browse Source 
Enable 64-bit bar emulation, if pbar is of type PCIBAR_MEM64, vbar will also be
of type PCIBAR_MEM64 instead of PCIBAR_MEM32

With 64-bit bar emulation code in place, we can remove enum pci_bar_type type
from struct pci_bar as bar type can be derived from struct pci_bar's reg member
by using the pci_get_bar_type function

Rename functions:
  pci_base_from_size_mask --> git_size_masked_bar_base

Remove unused functions
