Previously we prepared 32KB buffer to store guest VM boot parameters, in which
there is at most 17KB buffer for guest EFI memory map to accomodate ~400 EFI
memory descriptors. But this is uncertain to ensure working on all boards, now
change the algorithm that make the EFI mmap buffer adaptable with configured
MAX_EFI_MMAP_ENTRIES macro.

The coding guideline rules C-TY-27 and C-TY-28, combined, requires that
assignment and arithmetic operations shall be applied only on operands of the
same kind. This patch either adds explicit type casts or adjust types of
variables to align the types of operands.
The only semantic change introduced by this patch is the promotion of the
second argument of set_vmcs_bit() and clear_vmcs_bit() to
uint64_t (formerly uint32_t). This avoids clear_vmcs_bit() to accidentally
clears the upper 32 bits of the requested VMCS field.
Other than that, this patch has no semantic change. Specifically this patch
is not meant to fix buggy narrowing operations, only to make these
operations explicit.

The coding guideline rule C-PP-04 requires that 'parentheses shall be used
when referencing a MACRO parameter'. This patch adds parentheses to macro
parameters or expressions that are not yet wrapped properly.
This patch has no sematic impact.

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.
