This way we will have one
Xen binary which can be loaded by three boot protocols: EFI native loader,
multiboot (v1) and multiboot2.

x86: allow EFI reboot method neither on EFI platforms...
x86: properly calculate xen ELF end of image address

v10 - suggestions/fixes:
- replace ljmpl with lretq
(suggested by Andrew Cooper),
- introduce efi_platform to increase code readability
EFI_BOOT, EFI_LOADER and EFI_RS features. EFI_BOOT is equal
to old efi_enabled == 1. EFI_RS ease control on runtime
services usage. EFI_LOADER tells that Xen was loaded
directly from EFI as PE executable.

Add multiboot2 protocol support. Alter min memory limit handling as we
now may not find it from either multiboot (v1) or multiboot2.
This way we are laying the foundation for EFI + GRUB2 + Xen development.

fault load address from 1 MiB to 2 MiB. This way page table

Additionally, drop first 2 MiB mapping from Xen image mapping.
It is no longer needed.

Add multiboot2 protocol support for relocatable images. Only GRUB2 with
"multiboot2: Add support for relocatable images" patch understands
that feature. Older multiboot protocol (regardless of version)
compatible loaders ignore it and everything works as usual.

descriptor base address initialization

ented because it is quite simple and requires
limited number of changes, especially in __start_xen().
New allocator is quite generic and can be used on ARM platforms too.
Though it is not enabled on ARM yet due to lack of some prereq.

Additionally, GRUB multiboot2 implementation does not use u_phys anywhere.
So, replace it with basic well defined and used in implementation u32 type.
