Add a field (vdev_ops) in struct acrn_vm_pci_dev_config to configure a PCI CFG
operation for an emulated PCI device. Use pci_pt_dev_ops for PCI_DEV_TYPE_PTDEV
by default if there's no such configure.

This is a followup patch to fix the coding style issue introduced
in by commit "c2d25aafb889ade954af8795df2405a94024d860":
The unmodified pointer should be defined as const
Also addressed one comments from Fei to use reversed function call
in vpci_init_pt_dev and vpci_deinit_pt_dev.

Use nr_bars instead of PCI_BAR_COUNT to check bar access offset.
As while normal pci device has max 6 bars, pci bridge only has 2 bars,
so for pci normal pci device, pci cfg offsets 0x10-0x24 are for bar access,
but for pci bridge, only 0x10-0x14 are for bar access (0x18-0x24 are
for other accesses).
Rename function:
pci_bar_access --> is_bar_offset

Currently host bridge emulation and bar emulation are only for pre-launched vms,
use is_prelaunched_vm to check if it is for pre-launched vms when calling
init/deinit/cfgread/cfgwrite, also use is_hostbridge() to check if the access if
for host bridge, so that these functions can be unified for sos and pre-launched
vm in subsequent commits.
Move is_hostbridge function to vpci_priv.h so that it can be used by multiple
files.
vhostbridge_cfgread/vhostbridge_cfgwrite: return -ENODEV if the pci cfg access is not
targeted for vhostbridge so that cfgread/cfgwrite functions can be unified for sos and
pre-launched vm in subsequent commits
