- update the function argument type to union
Declaring argument as pointer is not necessary since it
only does the comparison.

When assgined a PCI PTDev to post-launched VM from SOS, using a pointer to point to
the real struct pci_vdev. When post-launched VM access its PTDev configure space in
SOS address space, using this real struct pci_vdev.

Rename vbdf to bdf for the following reasons:
Use the same coding style as struct pci_pdev, as pci_pdev uses bdf instead of pbdf
pci_vdev implies the its bdf is virtual, no need to prefix bdf with the v
prefix (redundant)

Remove vdev ops for partition mode, change related code to directly call the corresponding
functions instead
Remove struct pci_vdev_ops from vpci.h
Add @pre for pci_find_vdev_by_pbdf and pci_find_vdev_by_vbdf/partition_mode_vpci_init
Change the return value from int32_t to void to comply with misra c and
add ASSERT/panic in the functions (if necessary):
vdev_hostbridge_init
vdev_hostbridge_deinit
vdev_pt_init
vdev_pt_deinit
Still use pr_err in partition_mode_cfgread and partition_mode_cfgwrite to check if vdev cfgread/cfgwrite
access is aligned on 1/2/4 bytes, which is the only case that vdev cfgread/cfgwrite will return
nonzero, pr_err will be removed in subsequent patch titled "unify the sharing
mode and partition mode coding style for similar functions"
Remove @pre for local variables
Add ASSERT in partition_mode_pdev_init to check if pdev is NULL (user config
error)

Add vdev functions so they can be reused by both partition mode
and sharing mode code:
pci_find_vdev_by_vbdf: search for vdev by virtual bdf
pci_find_vdev_by_pbdf: search for vdev by physical bdf

core.c contains functions all related to pci vdev management, so it makes sense
to give it a more meaningful file name.
