efi.h: Do not use config options

Currently efi.h determines a few bits of its environment according to
config options. This falls apart with the efi stub support which may
result in efi.h getting pulled into the stub as well as real U-Boot
code. In that case, one may be 32bit while the other one is 64bit.

This patch changes the conditionals to use compiler provided defines
instead. That way we always adhere to the build environment we're in
and the definitions adjust automatically.

Attempting to use a toolchain that is preconfigured to generate code
for the 32-bit architecture (i386), for example, the i386-linux-gcc
toolchain on kernel.org, to compile the 64-bit EFI payload does not
build. This updates the makefile fragments to ensure '-m64' is passed
to toolchain when building the 64-bit EFI payload stub codes.

SPDX: Convert all of our single license tags to Linux Kernel style

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.

x86: Tidy up selection of building the EFI stub

At present we use a CONFIG option in efi.h to determine whether we are
building the EFI stub or not. This means that the same header cannot be
used for EFI_LOADER support. The CONFIG option will be enabled for the
whole build, even when not building the stub.

Use a different define instead, set up just for the files that make up the
stub.

efi: Add support for loading U-Boot through an EFI stub

It is useful to be able to load U-Boot onto a board even if is it already
running EFI. This can allow access to the U-Boot command interface, flexible
booting options and easier development.

The easiest way to do this is to build U-Boot as a binary blob and have an
EFI stub copy it into RAM. Add support for this feature, targeting 32-bit
initially.

Also add a way to detect when U-Boot has been loaded via a stub. This goes
in common.h since it needs to be widely available so that we avoid redoing
initialisation that should be skipped.
