Initialize Service VM vFDT by reserving hypervisor and pre-launched VM
memory regions.
The vFDT is copied to Service VM to the place just before the kernel
load address, and this needs to be fixed later when MMU module is
implemented.

For service and pre-launched VMs, the image loaders in ACRN
are functioning the same way as an in-guest bootloader such
as GRUB, which allows ACRN to load a guest image and start
directly from there and therefore skipping the firmware
initialization stage.
To re-use image loader code as much as possible, the image loader
logic is splitted into two stages, the loading stage and
environmental preparation stage. Most part of the loading stage
are common logic, and environmental preparation stage should
be completely arch-specific.
The best place for stage two loader logic is arch_vm_prepare_bsp,
which prepares vcpu register states based on the loaded image
(entry point, load address, etc.).
This commit refactors only the rawimage loader. Other loaders
are left for future improvement.

This commit moves struct acrn_vm under common header vm.h, and move some
x86-specific members of struct acrn_vm into arch_vm. This commit focuses
on struct cleanup only. API cleanup will be in future patch series.
The affected members are:
e820_entry_num
e820_entries
wire_mode
wbinvd_lock
vlapic_mode_lock
vcpuid_entry_nr
vcpuid_level
vcpuid_xlevel
vcpuid_entries
reset_control
pm
sworld_control
sworld_snapshot
intr_inject_delay_delta
Moved to common vm.h:
ept_lock -> rename to stg2pt_lock
ept_pgtable -> rename to stg2_pgtable
nworld_eptp -> rename to root_stg2ptp
emul_mmio_lock
nr_emul_mmio_regions
emul_mmio
emul_pio
To avoid circular dependency, some in-header helpers are also moved into
common vm.h.

Many of the license and Intel copyright headers include the "All rights

throughout the code (hypervisor, devicemodel and misc).

In order to make better sense, vm_elf_loader, vm_bzimage_loader and
vm_rawimage_loader are changed to elf_loaer, bzimage_loaer and
rawimage_loader.

Remove the acpi loading function from elf_loader, rawimage_loaer and
bzimage_loader, and call it together in vm_sw_loader.
Now the vm_sw_loader's job is not just loading sw, so we rename it to
prepare_os_image.

For the guest OS loaders, prapare_loading_xxx are not accurate for
what those functions actually do. Now they are changed to load_xxx:
load_rawimage, load_bzimage.
And the 'bsp' expression is confusing in the comments for
init_vcpu_protect_mode_regs, changed to a better way.

The patch splits the vm_load.c to three parts, the loader function of bzImage
kernel is moved to bzimage_loader.c, the loader function of raw image kernel
is moved to rawimage_loader.c, the stub is still stayed in vm_load.c to load
the corresponding kernel loader function. Each loader function could be
isolated by CONFIG_GUEST_KERNEL_XXX macro which generated by config tool.
