HV: remove vdev ops for partition mode

Browse Source 
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)
