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.

build: Drop CONFIG_SPL_BUILD guards in some cases

Given gcc-6.1 and later we can now safely have strings discarded when
the functions are unused. This lets us drop certain cases of not
building something so that we don't have the strings brought in when the
code was discarded. Simplify the code now by dropping guards we don't
need now.

imx: fix exception vectors relocation in imx27

Commit 3ff46cc4 fixed exception vectors setting in
the general ARM case, by either copying the exception
and indirect vector tables to normal (0x00000000) or
high (0xFFFF0000) vectors address, or setting VBAR to
U-Boot's base if applicable.

i.MX27 SoC is ARM926E-JS, thus has only normal and
high options, but does not provide RAM at 0xFFFF0000
and has only ROM at 0x00000000; it is therefore not
possible to move or change its exception vectors.

Besides, i.MX27 ROM code does provide an indirect
vectors table but at a non-standard address and with
the reset and reserved vectors missing.

Turn the current vector relocation code into a weak
routine called after relocate_code from crt0, and add
strong version for i.MX27.

Switch from archive libraries to partial linking

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
