HV: move bar emulation initialization code to pci_pt.c

Browse Source 
Create the init_vdev_pt() function to host bar emulation initialization code

Add design philosophy for bar emulation

Move common functions to pci.h as they are generic and can be used by other
files.

Rename is_valid_bar to is_bar_supported and keep it as a private local function
in pci_pt.c
