In the commit of 4e1deab3d9, we changed the
init sequence that init paging first and then init e820 because we worried
about the efi memory map could be beyond 4GB space on some platform.
After we double checked multiboot2 spec, when system boot from multiboot2
protocol, the efi memory map info will be embedded in multiboot info so it
is guaranteed that the efi memory map must be under 4GB space. Consider that
the page table will be allocated in free memory space in future, we have
to change the init sequence back that init e820 first and then init paging.
If we need to support other boot protocol in future that the efi memory map
might be put beyond 4GB, we could have below options:
1. Request bootloader put efi memory map below 4GB;
2. Call EFI_BOOT_SERVICES.GetMemoryMap() before ExitBootServices();
3. Enable a early 64bit page table to get the efi memory map only;

This patch has below changes:
1. rename mi_efi_info to uefi_info in struct acrn_boot_info;
2. remove redundant "efi_" prefix for efi_info struct members;
3. The efi_info structure in acrn_boot_info struct is defined as
same as Linux kernel so the native efi info from boot loader
is passed to SOS zeropage with memcpy() api directly. Now replace
memcpy() with detailed struct member assignment;
4. add boot_from_uefi() api;

ACRN used to support deprivileged boot mode which do not need multiboot
modules, while direct boot mode need multiboot modules at lease for
service VM bzImage, so ACRN postponed the multiboot modules sanity check
in init_vm_boot_info.
Now deprivileged boot mode was totally removed, so we can do multiboot
module check in sanitize_acrn_multiboot_info().
