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
regard.

- 331S: Literal value requires a U suffix.
- 612S: inline function should be declared static.
- 93S: Value is not of appropriate type. MISRA-C imposes strict type
checking: no comparison between signed and unsigned, etc.

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

Replace dynamic memory allocation in memory management with static memory allocation.
Since the static memory allocation can guarantee the allocation never failed, so
split_large_page and construct_pgentry don't need to return a errno any more.
Besides, the destroy_ept don't need to free page any more. Instead, it would memset
the eptp to 0 to make sure we can't walk this paging table again.

In order to allow these functions to be called without an associated
struct pci_pdev (for example, at the time of PCI bus enumeration), these
two functions can not take the struct vdev as input parameter.

- move the functions to access physical PCI configuration space from
pci_pt.c to the new file dm/hw/pci.c, so they can be accessed in
sharing mode as well. The new folder dm/hw is created in order to
move APIs talking to physical PCI devices out of dm/vpci.
- move the common vpci code from header file pci_priv.h to core.c.
- move file include/dm/vpci/vpci.h one level up. It seems the folder
include/dm/vpci is not necessary.
- This patch only moves code around, and doesn't make any logical
changes. Besides removes the static keyword from pci_pdev_read_cfg()
and pci_pdev_write_cfg()

Page table operation would not fault except:
1. the hypervisor it out of memory to allcate a page for page table operation
2. there is a bug with page table operation in hypervisor or devicemodle
While we assue that these would not happened in our platform when release, so
there is no need to check whether there is a fault with page table operation. However,
for debug version, we would panic the hypervisor if we can't meet the conditions really.

V4:
- Renamed members for struct pcibar and changed code accordingly
V3:
- Do not use ASSERT
- Use EPT_XX defines when claling ept_mr_add
- Report 64-bit MMIO physical bar to UOS as 32-bit virtual bar
(assume bar size is always less than 4GB), which removed quite some of
64-bit bar handling code
