Add a helper to allow loading an image within specified address range.
This will be used to load multiboot2 images later.

Normally vmlinux for arm64 is of ET_EXEC type, while if built with
CONFIG_RANDAMIZE_BASE (that is KASLR), it will be of ET_DYN type.
Meanwhile, physical address field of segments in vmlinux has actually
the same value as virtual address field.
Accordingly, in this case, it totally makes no sense to check for
validity of segments against physical memory ranges and, if necessary,
relocate them in elf_exec_load() on arm64.
This patch allows to unconditionally skip the check on arm64.

This patch adds core dump file support to ELF file loader. This can be
used by kexec based hibernation to load hibernated image, which is
from /proc/vmcore, a core dump file.

Move memory range variables
The common kexec code is currently using two global variables to keep
track of memory ranges. Other data is kept in a per-instance structure.
This mix is of per-instance and global variables is confusing and leads
to messy code in general. So let's not.
This patch moves the global variables into struct kexec_info and makes
sure that structure is passed along where needed. No logic is changed.

o Adding a new parameter to elf functions. This flag can be used to alter
the function behaviour. Currently only one bit is being used for skipping
the elf file len check while builing the elf info.

o Fix the logic to load a the files of type ET_DYN. Helpful in loading
the relocatable kernel to a different address than the address
executable is compiled for.
