The GPL and LGPL SPDX forms without an explicit -only or -or-later suffix are
deprecated and should not be used. Update the documention.
Somewhat unhelpfully at the time of writing, this only appears to be indicated
by the separation of the two tables at https://spdx.org/licenses/
The recent changes to libacpi are the only examples of deprecated LGPL tags in
tree, so fix them all up.
For GPL, we have many examples using deprecated tags. For now, just identify
them as such and recommend that no new instances get added.

Commit 68823df358 ("acpi: Re-license ACPI builder files from GPLv2 to
LGPLv2.1") added references to a "special exception on linking described
in file LICENSE", without actually adding such a file. Quite likely
COPYING was meant instead, yet then its text matches LICENSES/LGPL-2.1
except for some explanatory text (clarifying the "only" aspect) at the
top (and formatting). Hence replace the text in all the files with SPDX
references to LGPL-2.1.
Note that dsdt_acpi_info.asl had no license text. An SPDX tag is being
added there nevertheless.
