19c5342506 HV: remove vdev ops for sharing mode
Remove vdev ops for sharing mode, directly call the corresponding functions
instead of calling the ops callbacks (indirectly)

Remove alloc_pci_vdev() and merge its code into init_vdev_for_pdev() to simplify code

Remove @pre for local variables

Change the return value from int32_t to void to comply with misra c and
add ASSERT in the functions (if necessary) to verify the assumptions for debug build:
 vmsi_init
 vmsix_init
 vmsi_deinit
 vmsix_deinit

Add @pre for vmsix_init_helper and make it a void function, use ASSERT to verify
the assumption for debug build.

Add ASSERT in get_sos_vm

5767d1e141 HV: extract common code blocks to has_msi_cap and has_msix_cap functions
Define has_msi_cap and has_msix_cap inline functions to do sanity checking for
msi and msix ops, the corresponding code block in existing code is replaced with
a call to these new functions.

A few minor coding style fix.

93f6142d14 HV: declare and export sharing mode's vdev functions as global instead of static local
Export the following functions as global instead of static so that they can be
called/referred outside of the files where they are declared:
vmsi_init
vmsi_cfgread
vmsi_cfgwrite
vmsi_deinit
vmsix_init
vmsix_cfgread
vmsix_cfgwrite
vmsix_deinit

This is in preparation for removal of the sharing modes vdev ops, and call them
directly instead.

927c5172fa hv: vpci: fix MISRA-C violations related to variable declarations
78D: Global variable should be declared const.

Global variables should be declared constant wherever possible to
avoid unintentional modification.

27D: Variable should be declared static
  pci_ops_vdev_msi is not accessed by other files. Remove the declaration
  from the header and define it with the static qualifier; Because it's
  referenced by populate_msi_struct(), so move the define statements forward.

33D: No real declaration for external variable
  certain variables are available in sharing mode or partition mode only,
  so that the declarations in header files must be enclosed with
  CONFIG_PARTITION_MODE

576S: Function pointer is of wrong type. C90 requires the elements of an
designated initializer to appear in a fixed order, the same as the order of
declaration. C99 relaxes this rule but seems MISRA-C sticks to C90 in this

MISRA-C requires that the controlling expression of an if statement or

* update the U suffix of constant to let the type of operands
  to bit operations (&) is the same.
* update the type of 'i' from uint64_t to uint16_t in
  'profiling_set_control' since it is limited by phys_cpu_num,

99586e32cc HV:treewide:rename vm data structure
For data structure types "struct vm", its name is identical
with variable name in the same scope. This is a MISRA C  violation.

Naming convention rule:If the data structure type is used by multi
modules, its corresponding logic resource is exposed to external
components (such as SOS, UOS), and its name meaning is simplistic
(such as vcpu, vm), its name needs prefix "acrn_".

The following udpates are made:
struct vm *vm-->struct acrn_vm *vm

- it intercepts the IO requests for MSI Capability structure, emulates

  physical device.

- criteria to trigger MSI remapping: MSI Enable bit is being changed,
  Message Data/Addr is being changed when MSI Enable is set.
