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

ed113f570f hv: mmu: remove "##" for MISRA C
In the C99 standard, the order of evaluation associated with multiple #,
multiple ## or a mix of # and ## preprocessor operator is unspecifie.
 So it is unsafe to use multiple # or ## in a macro.

541f3713d2 hv: bug fix: normal world may get trusty world's pdpt page
Normal world would also setup 511 GB gpa EPT mapping when initialize.
So we couldn't know which the world is from the gpa. But trusty is so
special for that we know where it would get a pml4_page or pdpt_page.
As a result, we could simpler this by just return the pml4_page or
pdpt_page to it when it needs.

0391f84c83 hv: mmu: replace dynamic memory allocation in memory
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.

dc9d18a868 hv: mmu: add static paging table allocation for hypervisor
Add static paging table allocation API for hypervisor.
Note: must configure PLATFORM_RAM_SIZE and PLATFORM_MMIO_SIZE exactly as the platform.

Rename RAM_START/RAM_SIZE to HV_RAM_START/HV_RAM_SIZE for HV.
