To reduce the call to dynamic memory allocation, the patch tries to
alloate memroy together with hypervisor when hypervisor is being
relocated by efi stub code. The memory allocated will be right at the
end of HV memory. Three structs will be done in this way: 1) boot_ctx,
which saves EFI boot state and is passed to SOS; 2) multiboot_info,
faked multi-boot header for passing boot info to hypervisor; and 3)
multiboot_mmap, e820 mmap structure.
after this, the EFI stub code (which boot hypervisor) will only have 3
to dynamic memory:
1. the call for hv binary and the 3 struct;
2. the call to CPU boot trampoline code;
3. the call to alloc mmap buf when inquery memory layout from UEFI FW;
