Add 'struct vpci_ops *ops' to 'struct vpci' so we have clearer structure:
- struct vpci: include struct vpci_ops pointing to different callback
functions for partition or sharing mode repsectively.
- struct pci_vdev: includes struct pci_vdev_ops to handle different vpci
functionalities:
hostbridge emulation
passthrough device BAR emulation
msi/msi-x remapping
This patch moves the code around but doesn't change the underlying logic
in terms of PCI spec handling. More detailed implementation:
- create new file partition_mode.c to house the implementation of partition mode
regarding the vpci layer.
- vpci.c: only keeps the abstract code which calls vpci->ops to functions
in partition_mode.c, and potentially to sharing_mode.c.
- the following functions are moved to partition_mode.c and renamed with
partition_mode prefix.
- vpci_init() -> partition_mode_vpci_init()
- vpci_cleanup() -> partition_mode_vpci_deinit()
- pci_cfg_io_write() -> partition_mode_cfgread()
- pci_cfg_io_read() -> partition_mode_cfgwrite()
