To: u-boot
The zynqmp image format has support for inline partitions which are
used by FSBL to describe payloads that are loaded by FSBL itself.
While we can't create images that contain partitions (yet), we should
still at least be able to examine them and show the user what's inside
when we analyze an image created by bootgen.

v1 -> v2:
- prettify defines
- fix offset and size outputs
- add u-boot as payload target
- align CPU names with bif
- add shift constants
- add U-Boot as potential partition owner
- mention documentation source
- add HEADER_CPU_SELECT_A53_64BIT define

We will add support for ZynqMP bif input files later, so let's move
all structure definitions into a header file that can be used by that
one as well.

To: u-boot
The officially described way to generate boot.bin files for ZynqMP is to
describe the contents of the target binary using a file of the "bif" format.
This file then links to other files that all get packed into a bootable image.
This patch adds support to read such a .bif file and generate a respective
ZynqMP boot.bin file that can include the normal image and pmu files, but also
supports image partitions now. This makes it a handy replacement for the
proprietary "bootgen" utility that is currently used to generate boot.bin
files with FSBL.
