Runtime relocation has been made the default for microblaze, so do the
following cleanups:
- drop all manual reloc codepaths in start.S
- drop all STATIC_RELA ifdefs, as it is now enabled unconditionally in
Kconfig

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.
By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.
The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
sections are empty. relocate-rela will fill them and output file is
u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections
Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).

Enable u-boot.elf recreation from u-boot.bin to prepare for removing manul
relocation. Enable option for big endian configuration but it is not used
too much that's why it is completely untested.
By supporting this system there is a need to define LITTLE/BIG endian
Kconfig options to pass -EL/-EB flags.
Full command line for u-boot.elf recreation looks like this:
microblazeel-xilinx-linux-gnu-objcopy -I binary -B microblaze \
-O elf32-microblazeel u-boot.bin u-boot-elf.o

GCC's garbage collector works for Microblaze for quite a long time but none
has enabled it.
The same change has be done for example by commit fac4790491f6 ("arc:
Eliminate unused code and data with GCC's garbage collector").
Before:
text data bss dec hex filename
588760 33592 39192 661544 a1828 u-boot
After:
text data bss dec hex filename
504504 32164 38608 575276 8c72c u-boot
Which saves almost 15% of memory footprint.
Also group symbols/functions to proper section.

In order to support the compiler providing information used within
Kconfig itself we cannot have the compiler be determined by
arch/*/config.mk as we will not be able to evaluate that yet. Given
that most documentation tells people to specify CROSS_COMPILE, remove
these references.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The syntax
CROSS_COMIPLE ?= <cross_compiler_prefix>
does not work because config.mk is parsed after
exporting CROSS_COMPILE.
Like Linux Kernel's arch/$(ARCH)/Makefile,
we must write as follows:
ifeq ($(CROSS_COMPILE),)
CROSS_COMPILE := <cross_compiler_prefix>
endif

This is minimum code required to be able to use device-tree
for u-boot initialization.
Currently only for device driver initialization.
Linker script change ensures DTB to be aligned
for both options CONFIG_OF_EMBED and CONFIG_OF_SEPARATE.
