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()

MISRA-C requires that there should be no unused parameters in
functions.
In some cases, we will keep the unused parameters.
vmexit handler is one example. It is used as function pointer.
Some of the vmexit handlers use the input parameter 'vcpu', some of
them don't. We still need to keep the unused parameters 'vcpu' for
those handlers don't use 'vcpu'.
This patch removes the unused parameters that is not being used
unconditionally.
v1 -> v2:
* remove the non-implemented API 'vlapic_id_write_handler'

- Converted MACROS to functions
- Defined pci_bar_type enum
- Defined pci_bdf as union instead of uint16_t to eliminate macros
- Use L or UL postfix after unsigned integers

V4:
- If pci device is not found in the PCI mapping table, just return without
throwing any error message

- Moved error checking code to cfgread/cfgwrite ops
V3:
- Do not use ASSERT
- Call the cfg read/write ops defined in the vm description
V2:
- Fixed MISRA violations
